What are /r/ColorBlind's favorite Products & Services?

From 3.5 billion Reddit comments

You get a phone with Android OS, take this test and do it in front of her.

If she still says you're not colorblind and that you're lying and acting, well then you have bigger problem with your mom than with your color vision.

I took a stock Rubik’s cube, in its traditional colors, and printed three distinct symbols, nine each, on Brother 0.75" white-on-clear label tape, cut them all to fit, and stuck them on the three ambiguous colors.

In shortest, deuteranopia is red/green blindness, while deuteranomaly is red/green deficiency.

The difference is obvious, the first is total absence of red/gren perception and the world seems blue/yellow colored to people who have it - so no purple, green, orange, pink, or red perception in any variation, only blue/gray/yellow colors are perceived.

Deuteranomaly is milder form. People with it still perceive red/green dimension (and thus purple, orange, green, red, pink colors) but in a deficient way so that all those colors are more similar to blues and yellows compared to normal vision, which is why they fail color vision tests.

Simplest way to find out is by doing CBC test for Android (make sure you have no screen/color filters turned on). If you get severity less than 90/100 then it's almost certainly deuteranomaly (the lower the score the milder it is - 0 is normal vision). If you get a score higher than 90, then you have either strong deuteranomaly or deuteranopia. Those two are very similar and no online color vision test can diagnose the difference correctly. A lot of optometrists/ophthalmologists can't as well, you'd have to find a specialist for color vision to do that.

Give him this test and represent it as just a game of course. The test was actually made by a guy who's severely colorblind and wanted to test his young kids for colorblindness as well. I think if any test is applicable to children, it's that one.

Just a note regarding the test and your screen. Screen colors must be on default, so turn off ANY color filter if you maybe have it on and do the test in a darker room. The task is to tap on the little colored squares as soon as you spot them, so as quick as possible. At the end, the test shows the score as a combination of total points, PDT and severity scores. You can paste it all here if you want.

ColorBlind Pal lets you use a phone camera to identify colors. Point a reticle at what you need to identify and it tells you what color that is. Hopefully that helps?

Ah okay. Also, the normal eye doctor probably doesn't know much more about colorblindness than you do. All they'll do is give you the quick test with the dots and numbers again. However, if he has reason to believe that the colorblindness is new, he should go to a doctor. Almost everybody is born with it.

I'd recommend this app, it's the most accurate test I've found: https://play.google.com/store/apps/details?id=ch.colblindor.colorblindcheck (I think there's an iOS version as well)

May I ask why do you need a confirmation from an optician if you already know for sure that your son is colorblind? If you really need to get an official diagnosis for some reason, you don't take him to optician but to an opthalmologist (eye doctor).

You can give him color blind check test for Android to have a better insight into his type and severity of CVD.

Another hack here who works in a creative filed. If it falls on me to come up with the colors for a project. I'll use this website to generate a few different options, and then let the client choose which one to use.

The indoor Enchroma glasses may be useful for you. Outside of their intended use on screens I've noticed they don't enhance green as well as the sunglasses, but red and orange still pop. They do noticeably remove a yellowish tint from the environment, especially from neutral surfaces like drywall and concrete, and blue becomes more vibrant.

Sounds like protan (I think). Have her take an online test, like the Ishihara test, or for more precise results have her take the test in this app.

Yup something very weird is going on with your vision. The first A on the left is just contrasted from the background meaning there is mostly brightness difference. All three RGB values are just increased in that letter compared to its surrounding background color, thus everyone should easily see it.

Have you ever tried this test ?

Confusing dark purples and dark blues with black, and light yellows with white, is almost a definite sign you have blue-yellow color vision deficiency. That one is much rarer compared to the other type - red/green deficiency - which is what 99.5% of all colorblinds have. That's why majority of color vision tests on the internet don't test for it and you pass all of them thinking your color vision is completely normal.

You can do these next tests to confirm:

• Do THIS TEST on android phone and write down points, PDT and severity scores.

• Watch THESE three YouTube videos, especially the hard level version, read the descriptions bellow, and write down the problematic timings if you have them.

As I understand it, any test that involves displaying something on your pc screen or phone has the risk that the colours won't be displayed accurately, so I guess if you have weak colour blindness the tests may not always work.

There are tests linked in this sub which are accurate as far as I know. I've also used the following app on my android phone (Not sure if its available for iOS)

https://play.google.com/store/apps/details?id=ch.colblindor.colorblindcheck

Ultimately the most accurate check will be with a medical professional though I think.

I have always used color-hex.com when making themes for forums and other art assets. It gives the relative tints, shades and other colors.

Also a cool website recently posted here is paletton.com. I have not had a chance to use it but it looks really well organized and powerful. I plan to use it on my next project.

Cheers!

I'm not sure what tests you have tried but if you haven't already and If you have an android phone try this app. It's widely regarded as the most accurate CVD test.

You might have very mild deuteranomaly. What do you get on these two tests:

• CBC test for android phone. Write down points, PDT and severity scores.

• watch the hard level video, read the description bellow, and write down the problematic timings if you have them.

If you only can't see the gap on the 14th one, your vision is probably normal. I think mildest red-green deficiency have problems from 10th, 11th onwards.

These next two tests will give a better analyzis of your color vision

• Do THIS TEST on android phone and write down points, PDT and severity scores. For higher accuracy, if you want, you can do the test on a couple of different screens and a couple of times on each of them, and take some average result.

• If you don't have Android and don't want to play with Android emulators, watch THESE three YouTube videos, read the descriptions bellow, and write down the problematic timings if you have them.

Nobody sees this clearly because it's like 5% saturated green. It's barely visible for everyone. The only potential problem is that you see it as gray and don't recognize it's greenish, but that might just be your lower screen quality. If you're concerned that you might be colorblind just:

• do THIS TEST on android phone and write down points, PDT and severity scores.

• If you don't have Android and don't want to play with Android emulators, just watch THESE three YouTube videos, read the descriptions bellow, and write down the problematic timings, if you have them.

I use navbar apps. Lets you customize color, choose a background, do things like add in a battery meter, etc. It's pretty cool and a lot better than just having it black IMO.

No need. Or

> As a rule of thumb, push on your cheek to feel the equivalent of a rare steak. Push on the tip of your nose to feel the equivalent of a medium steak. Push on your forehead between your eyebrows to feel the equivalent of a well-done steak.

Do the color blind check test for Android. Just tap on the colored squares as fast as you can, and report back here your PDT, points and severity result. It's possible that you have some form of redgreen deficiency.

You don't have a Windows laptop/computer? If you have you have a description in the post how to install it there. Basically you just install blue stacks - link and then install the test in it.

Protan and deutan types are A LOT more common and they make up about 99% of all colorblind people. That is why almost all vision tests you find on the internet are oriented on testing red/green vision only (including Ishihara) and not blue/yellow (tritan) deficiency.

Color confusions characteristic for tritans are all the color pairs that differ in blue and/or yellow colors. Blue - purple is not precisely tritan confusion, but bluish indigo (or violet) - purple is. Your brain sees violet as a combination of dominantly blue and some red nerve signals, and it sees purple as a combination of a bit less blue and red nerve signals. Tritans have decreased blue response so they perceive that difference between those two similar blue levels as negligible, which is why the difference between those two colors (more vs less blue signal) is very small, so both colors appear as the same purple color. In case of red/green deficiency, they both appear as blue.

The best online tests that detect tritanomaly pretty accurately are these two

Color blind check test for Android.

colorlite test - just do the tritan (blue) test.

They're only as accurate as your monitor is calibrated. If you're getting normal vision you're probably not, at the very least, colorblind enough to really have to worry about it affecting you on a daily basis. At the same time, though, it's good to go to the doctor every once in a while just to check on your personal health. If you want to ensure the result is accurate, do the EnChroma test on multiple screens. Additionally, this app gives the most accurate results that you can get on a screen.

They exist, and you can use essentially a cyan-colored lens. I haven't been able to source one myself, but I haven't tried too hard.

Would an app meet your needs? This is my go to for sharing my dichromacy:

https://play.google.com/store/apps/details?id=asada0.android.cvsimulator

Color differentiation does get worse as one ages. However, if it's changing at a significant rate and it's worrying you go to an optometrist. It could be an early warning sign of an eye disease. Now, if you'd like to test if you're colorblind, go to this webpage. Additionally, if you have an Android device, download this app and take the test on it. This app is regarded as the most accurate test you can get on a device. The most accurate tests, however, can only be performed in-person due to there being variations between screen color calibration settings. Hope this helped!

This app hasn't been updated in years, but it works on my pixel 3a: https://play.google.com/store/apps/details?id=com.colorblindpal.colorblindpal&hl=en_US&gl=US

In the filter mode, you can select orange-red, and the amber lights stand out with everything else reduced to gray scale, including the green lights. It works both live and with still photos.

I just used my app called color blind pal on android and I am able to hold cables like you did in my hand and have it tell me what is what. Do you have an android? link to app with its own screen shots here https://play.google.com/store/apps/details?id=com.colorblindpal.colorblindpal&hl=en_AU&gl=US

Tritanopia is dichromacy where S cone type cells are completely missing, which causes complete loss of blue-yellow vision (only pink-teal vision is present, yellows appear as gray/white and purples are dark gray). So there is just one severity of it. Different severities are in anomalous trochromacy (protanomaly, deuteranomaly, and tritanomaly). So in tritanomaly, just like with protan and deutan types, there's basically a slider of near normal vision (slight severity) to strong severity (almost tritanopia).

The task is to tap on the little colored squares as soon as you spot them, so as quick as possible.

Enchroma test is not so reliable, especialy not for detecting mild tritanomaly which from your description seems like is the deal with your vision.

• Watch here the hard level video, read the description bellow, and write down the problematic timings.

• Do THIS TEST on android phone and write down points, PDT and severity scores.

P. S. As above commentator has said, tetrachromatic stripe test is a total bs lie :) I remember it being on the news in my country and everyone laughing about it. There has only been confirmed 2 or 3 Functional Tetrachromats in the world, ever, and very special Rayleigh match test is required for it because tetrachromacy can never be tested on RGB electronic screens using only 3 primary lights :)

Seeing only reds and blues as gray is definitely very rare. Protanopes (red-green deficiency) see reddishpinks and teals as gray, while tritanopes (blue-yellow deficiency) see purples and yellows as grays, so it's maybe possible that you partially have both - red-green and blue-yellow deficiencies (achromatomaly). We can't say for sure until you do certain tests.

Make sure all color filters on your screen are turned off, including eye care, blue light filters, etc. It's important that the colors on your screen are on default.

Not enough to be certain because some screens simply produce lower blue levels, but it is possible blue-yellow deficiency.

It was interesting, I let my family members watch me do the color blind check test and they were astounded that some of the squares took me so long to find, but it was also interesting that on some of them I saw them before they did. My dad kept saying stuff about 'false positives' because I was tapping squares he couldn't see, but at the end I was able to show him in the results that I had no wrong touchpoints.

I'm not entirely sure I understand what kind of app you need, but if the problem is your colorblindness and not being able to recognize colors correctly, then this app for android can maybe help you? Or this one for iOS.

Yes there is, it's called Color Blind Pal: https://play.google.com/store/apps/details?id=com.colorblindpal.colorblindpal

Its main purpose is to use the camera to tell colorblind people what color something is, but when you click the 'I' icon you can tap 'color blindness type' and select 'simulate Protanopia'. Then go back to the main screen, and click the 'inspecting color' button so it changes to 'filtering colors', and make sure the mode is set to 'shift' at the bottom.

Now you can use the camera to see what the world is like with protanopia. The app isn't really straightforward to use, but it does work once you know how to use it.

I occasionally hear the question and I give a brief explanation of what I see. I highly recommend "Chromatic Vision Simulator" [Android] [Apple] as it lets you select your specific color deficiency ("Protanope," "Deuteranope" and "Tritanope") as well as normal color vision. I use the app to demonstrate to people what I see versus what they see. I explain that although it's not an exact replication, it's somewhat close. It's very eye opening (pun intended) because they can get an idea of the differences and they can download the app on their phone if they want to explore more.

Disclaimer: I did not write and am not involved with "Chromatic Vision Simulator"... I just really like the app and it is free.

Deut here... can't see a thing. It's just a load of coloured dots. The "Color Blind pal" application on my phone picks out "16".

If you have trouble with LEDs (is this light blinking red, yellow or green?) there are smartphone apps that can help. There are also red and green filter lenses that you can keep on a keychain which can help you to identify colors.

I haven't used that one, but I do use these:

https://play.google.com/store/apps/details?id=com.mkrscope.ledscope_trial

https://play.google.com/store/apps/details?id=jp.gr.java_conf.geoteru.colorpicker

In my experience, devs are very open to suggestions to help those with CVD - especially small indy teams. The main developer of Button Up!, a similar-but-not-really puzzle game was kind enough to listen to my input early on and add hints in the form of size differences and dots in the circle (which indirectly lead to the current theme of stitching buttons, actually!)

Describing your color confusions is never enough because literally every single type can confuse any two colors. You have to do the test.

I recommend these two tests to everyone since they are the most accurate I know of

Color blind check test for Android.

RGB anomaloscope for PC.

The screen of my previous phone was capable of displaying reds so intense that they looked unreal to me. I was looking at the red candies in Candy Crush Saga (played it for the lulz, but it's the best example) and I was like "is this how normal people see red? gross".

I'm a big fan of "Pixie"

It lists out the RGB, hex, and HTML codes and even lets you open a Windows colorpicker window. It's a really tiny and accessible program and so far has not failed me once.

Not aware of anything like it. What I have used though in the past to help me when I am a little confused is a free program called Pixie. It does the following; "Run it, simply point to a color and it will tell you the hex, RGB, HTML, CMYK and HSV values of that color. You can then use these values to reproduce the selected color in your favorite programs. Pixie will also show the current coordinates of your mouse pointer. " I find occasionally knowing the RGB values helps me get on the right track :) Not perfect, but something. Link

Edit: I just looked up for other apps and found an apple/android app called Dankam that may help, though I haven't used it.

Instant Eyedropper can give you the RGB colors, but doesn't put a name with them. I still like it because it's small and fast and easy to use. I can always paste the hex into Color Name & Hue if I need to. Ideally I would combine these two things to be like Colorblind Assistant, but Instant-Eyedropper isn't open-sourced.

You can use any image editor, I'm on a new computer so I used https://www.photopea.com/ which is basically Photoshop lite in your browser. If you paste an image you can click on the Channels tab on the right hand side to look at the individual color channels. If you want to actually modify the image you can use the tools in Images > Adjustments, e.g. Color Mixer.

Hmm, I've been using Chrometric to see how pages look for different types of colourblindness. It's open source so you could probably check out the filters they use.

That website is not a good indicator for colorblindness type.

Just do the color blind check test for Android.

RGB anomaloscope is very good one as well. If your resulting line falls from the center to the down-right then you're protan, if it stays near-flat you're deutan.

I'm interested to know what points and severity score you get on this test. Based on that we'd maybe be able to tell what percentage of people here would pass that OCV test.

In my experience, if someone says they have difficulty of distinguishing certain shades of colors, it almost certainly means they have some type of color vision deficiency. Just like the majority of us here, you are not blind to colors, you have just decreased sensitivity to some of the colors. Most of the times, colorblindness is exactly that - color vision deficiency.

I advise doing this vision test and see what you get.

Yeah that's a big mess.

If you have an android phone try this app instead. It's widely regarded as the most accurate CVD test.

Check out "Color Blind Check" https://play.google.com/store/apps/details?id=ch.colblindor.colorblindcheck

If you have a really hard time distinguishing vivid red from dark yellow, It sounds like strong protanomaly or protanopia. If you can find an android smartphone, it would be good to do THIS TEST. Just write down your points, PDT and severity scores. For higher accuracy, if you want, you can do the test on a couple of different screens and a couple of times on each of them, and take some average result.

P. S. If you don't have android phone, you can install the test on windows via bluestacks android emulator.

You don't seem to have deuteranopia if you easily see the difference there. Have you ever done this test? How does the top gradient appear compared to the middle one in this image ?

Firstly I must comment those descriptions on that website

Deuteranopia:

> yellow and green appear red while blues look violet

Protanopia:

> Orange, red and yellow look greener and colors are dull

For such a popular website that comes out on second place when you google for "colorblind test", I can't believe how inaccurate that description is. In both protanopia and deuteranopia, green, yellow and red appear yellow. Yellow and green definitely don't appear reddish, and blues definitely don't appear violet (blue+ slight red) in any type nor severity of red-green colorblindness. Red-green dichromats don't have any red-green color vision and only see in blue-yellow, thus violet appears blue not the opposite.

As for your color vision, just do this test on android phone and come back with results if you want to discuss them. It will diagnose your vision in 2-3 minutes.

Two people with protanopia and deuteranopia actually see all the identical colors, but not in the same places. I explained the difference more profoundly in this comment. There is no type in-between protan and deutan because they both fall under the same red-green color deficiency. There are many slightly different eye cone positions in both protan and deutan cases (there are no two specific L and M cones sensitivities for each type, rather than dozens of different positions), so you almost certainly lean more towards one type than towards the other one. Two guys with deuteranopia for example, might have pretty different visions and brightness sensitivities to the EM spectrum.

And btw, you should do the color blind check test (you need an android phone for it though). Come back with results (points, severity, PDT score) if you want to discuss your vision.

Perhaps the moderators could add the Color Blind Check app to the masthead on the right? It seems to be one of the best tests out there, it does exactly what you're interested in, it shows the strength and the type (or a mix of types as the case may be sometimes): https://play.google.com/store/apps/details?id=ch.colblindor.colorblindcheck

Sure, it's for Android smartphone though.

https://play.google.com/store/apps/details?id=ch.colblindor.colorblindcheck&hl=en

If you don't have android you can install some Android emulator in Windows and then install the program from there.

I accidentally discovered my friend's fiance was colorblind right before their wedding, like 2 months before. I had an app that simulates different CVDs on what the camera sees.

https://play.google.com/store/apps/details?id=asada0.android.cvsimulator&hl=en_US

Anyways I think I freaked her out. She said no one in her family was. I told her that he dad had to be too. So she called him while we were all at the bar. He tells her, "Nah Im not colorblind. I just sometimes mix up red and green or blue and purple." I told her that means he is colorblind. So both he and his daughter learned in the same night.

If they both went through their whole lives, including planning a wedding and picking out colors for shit for a year with her not colorblind fiance, I think everything will be alright. It was hilarious to hear that were arguing about colors a few weeks before that and now I had vindicated his claims.

They been married almost a year now tho

After some research, I've found an app with a test I've not completed before: app

The results suggest 6 protan, 3 deutan, 0 tritan deficiencies.

I assume this is out of 10, but what's new to me is that I might be protanomolous and deutranomalous, but only half as much.

I made an app for color matching, maybe it will be helpful for you. It is available on Android and completely free (with no ads). I would appreciate if you can give any feedback about it. https://play.google.com/store/apps/details?id=com.styleur.user.colour

Actually, the game has been out for a while, and I need all the help I can get to solve it's current problem. On over 50% of devices I've tested, the game crashes on start. If you get it and it works on your device, please press the "email me" button and send me your device specs so I can add it to the list of working devices.

The game is free and ads are opt-in only (they can be disabled with the press of a button) with an optional donation button. My plan as of right now is to fix the crash bug and release colour-blind support on the same update, but I'm having a hard time with the crashes. I might have to remove Google Play Games support, IAP support, and ads support to get it to work, but I would rather have a working app than one I can monetize (what little there is to monetize).

Also, I'm in high school so I mainly make games as a hobby, but also to build up a small portfolio. Since a few people rated it mentioning colour blindness, I figured I might as well add a new feature along with stabilizing it.

Ps. Sorry for rambling, it helps me think.

Im male. I had a game that utalized things like that hues test on my previous android. Let me find it. but i will try those tests as well.

Edit: after taking the test i have an error of 56 and a slight tritan/blue deficiency

There is an Android version too :

Colorblind Vision -- Realtime color blind vision – Use your camera to look through the eyes of the Colorblind. -- Colorblindness test – Take a classic Ishihara Test (dot test) to classify if you are colorblind. Build your own tests to say anything you want. Ever wanted to write a message that a colorblind person couldn't read? -- Learn about color blindness – Learn more about colorblindness, what it is, how it affects people, and the advantages and disadvantages of it. -- Extract colors - Pull out individual colors. Perfect for anyone who is colorblind. Can be used while playing board games to distinguish the pieces, or to help you tell if your clothes match.

And another one called ColorBlindness SimulateCorrect

You could check out this site if you haven't already, they're high quality and trustworthy but highly expensive.

There are also many other cheaper types ofc, tho I'm not sure how affective they are

Hope this helps

I followed the link in the picture, gave the game a try. Honestly, using the number for the nodes gets around most of the issues with the colors.

I tried both color schemes. I switched away from the Alternate because the colors were so drab, at least on the puzzle that I was on (not using the full palette)

I've played similar games. I like it's using non-standard grids (i.e. not x-by-x squares)

Graphic designer here. I do find it hard at times, but one of the first things I do is determine a palette. color.adobe.com is wonderful in that regard. I also have a few bookmarked sites for hex codes for colors, so once I get a starting point, I can choose complimentary/contrasting colors and keep faith in color theory that things will work well together.

Find an image editing program that uses a colour wheel. Paint.NET for windows has one, and is free. GIMP probably also has one. Screenshot the colour wheel, paste it in to a new image and crop it down to just the colour wheel. Start a new layer and draw on top of it with black. Save it as a jpg or png and upload it to reddit.

I can't quite figure out a straightforward explanation. Is it possible that you had an underlying congenital red-green colorblindness before your retinopathy kicked in? You can try taking a test using just your "good" eye.

> ...assist those with Protanopia, Deuteranopia, and Tritanopia.

according to this blog post it should also support tritanomaly mode

I think it's out of publication now. [It used to be used to test aviation pilots in the U.S. I know, but don't think it's available anymore.] The no.'s look too far spread apart & real wonky even for normal vision I think. *Try looking for PIP colour test.

Incidentally, I found someone in an old thread asking this very question in 2008 as they were unable to find them on the web. Personally, I don't think it's a real reliable plate test for anyone to take compared to the more recently updated 38-plate Ishihara book. Honestly, I prefer the HDD test as it's a lot more modern & quizzes even tritan CVD; whereas, Ishihara only helps identify it in its four 'identification' plates is a geared red/green CVD test.

+Hope this helps!

Synesthesia and colorblindness are two very different disorders. No it doesn't have anything to do with colorblindness. If you think you might be colorblind, do this test. Though considering you describe the world as "so colorful", I doubt you are. That's not something coor vision deficient person would say.

That's not how that app diagnoses color vision. You've done the wrong test.

Here's the link

color blind check test.

Seems like red-green deficiency (protan or deutan). There's no real way to know until you do the isiob test. You can try the color blind check test for Android.

Their tritan test is very accurate. It literally discovers the smallest deficiency in blue-yellow vision, of course considering the test is done on the calibrated screen. If you score 3/10, it's pretty certain you have moderate-strong tritanomaly. Most of simple red/green vision tests are not exactly fully independent of blue/yellow vision, so strong tritanomaly can falsely give mild protan/deutan results on those kind of tests, even if your red/green vision is fully normal.

Color blind check test for Android has been proved on this sub as the most competent test so far, and the one that distinguishes protan/deutan/tritan types pretty accurately. Just pay attention to your PDT and severity scores. For example PDT 0-0-10 means the test found your vision to be 0% matched with Protan deficiency, 0% matched with Deutan deficiency, and 100% matched with TRITAN deficiency. 0/100 severity result is perfectly normal color vision, while 100/100 is dichromatic. Red/green and blue/yellow dichromats usually score in the 1300-1600 point range, monohromats about 300.

Just a note, for the test to give most accurate result, do it on a phone using sRGB color space (check your display settings), and of course turn all color/visual filters off, including blue/night eye saver. Colors must be completely on default.

In order for any online color vision test to consistently give accurate results, your screen must be calibrated and that test must be properly designed of course. Someone with normal vision would never get mild or moderate protan result on any test, so it's a pretty high possibility that you're protan. I suggest doing the colorblind check test for Android on a phone where all color filters are turned off. In case your phone uses wide color gamut you'd have to set the color gamut (in your display settings) on narrower sRGB color space for the test to produce maximum accuracy.

Your confusion comes from the god damn wrong English term that preoccupated this sub's name as well - color blindness. It's not colorblindness, it's color vision deficiency or CVD. There's like 20 people per month who come here with the same confusion as you have, so this should really become the top stickied post.

You're not blind to colors, you can see the world in color, but in fewer colors than normal vision, which is why you fail that test. Colors look normal to you because you've never had other people's perspectives to compare your vision to. You've learned to call the colors the same as others, just like the rest of us here, but you don't perceive those colors the same.

Do this test for Android next to your friend or family member that has normal color vision, and you'll understand. They see "invisible" colors my dude.

That test is interesting, i've always thought i had moderate deuteranomaly but from the several tests i get back it seems as though its very severe deuteranomaly or even deuteranopia. here are the results btw. Does anyone know what the most "reliable" test is out there?

Blue and Yellow Don't Make Green: How to Mix the Color You Really Want- Every Time https://www.amazon.com/dp/0967962870/ref=cm_sw_r_cp_api_glt_fabc_D875GVZB4HNQ84JXAFV3

Green-brown is a classic confusion for redgreen color deficiency. Colorblindness is a wrong term actually. The correct one is Color Vison Deficiency because it can range from almost normal vision to being fully redgreen blind. Majority of people in this sub are CVD and can as well identify all primary colors.

If you think that you have it, just do the test

>I have a program generate every possible shade of pure green, red, and blue, they all look normal to me. No browns or greys.

That same thing applies for someone who has deuteranomaly or protanomaly. They don't see either browns or grays when they slide through pure R, G and B values. Everything you see is normal to you because it's been everything you've ever seen. You didn't have other people's perspective to compare your vision to, so you're not really reliable to conclude whether the colors you see are normal or not. Only color vision tests can conclude that.

>I wonder, how can this be? I've tested for abnormally good color vision, and I can see all the plain colors fine. So, how can I not see specific shades of dark red? I don't understand how a mixed color could appear off to me when all the pure colors look normal. I also don't understand why darker shades seem to cause more issues. In particular, my mother has recently been diagnosed as mildly green deficient (not enough to actually be colorblind though). In her case, it appears to be dark, sickly green that appears grey to her.

If you're a male and your mother is redgreen coor deficient, then you're 100% redgreen color deficient as well. If you're a female and your father has normal redgreen vision, then you'll have redgreen normal vision.

There's two possibilities I see here:

1) Your eye doc diagnosed you correctly and you're tripping things out.

2) your eye doc has missed to diagnose that you have some very mild form of red-green deficiency.

In either case, you can try Anomaloscope test and see whether you get some resulting line.

CBC test for Android is considered as one of the most precise tests that exist online. Tough keep in mind that your phone has to have sRGB color space applied for the test result to be viable.

For green colors it is normal, but I don't think tritans are supposed to see red darker and grayer. S cones that are problematic in tritanomaly, don't activate at all for colors in the red spectrum, so tritans shouldn't be experiencing any brightness loss on those colors.

You can try the color blind check test for Android.

Unfortunately that test is only made for Android platform. The only other option is to download bluestacks Android emulator for windows and install it from there. Thoguh you need a decent computer for the test to work properly. On my older generation Gateway lap top with poor graphics cars, it doesn't work as intended to, while on my desktop computer it works like a charm.

What do you think of color scheme designers? Back when I thought I could hang in graphic design I used these all the time to make sure I wasn't bollocking up everything.

I work in a small architecture firm, and do all of the artistic renderings of our projects. I rely on the help of my coworkers on fine tuning colors and make use of paletton and encycolorpedia.

U wot m8? Not colorblind, it's a light brown, though there is a heavier discussion on the exact color to describe it

Also, it looks like the extension actually makes some color /harder/ to distinguish. For example, on the following page:

The color for "Android" is much closer to the blue (is that it ?) background.

If you have an android phone try this app. It's widely regarded as the most accurate CVD test.

You seem to maybe have a bit more severe red/green color vision deficiency.

You can do the color blind check test on Android to see your exact type and severity. Just tap the little colored squares as soon as you notice them, so as fast as you can.

My best recommendation would be that you don't get him any glasses without knowing his type and severity of colorblindness first.

Install this test on your phone (requires Android OS) and make him somehow do the test if he's not uncomfortable with that. You can maybe say that you've found an interesting app online and show it to him. At the end, test shows type (protan, deutan, or tritan) and severity of colorblindness (number/100). 0/100 is normal vision, while 100/100 is severe deficiency where glasses can't help at all.

Glases are the most effective for mild deutans, which would be severities in the range of about 10/100 - 40/100. They work as well for moderate (40-80), but the stronger the severity is and the closer to 100/100 he is, the closer is glasses effectiveness to zero and the bigger chance is they'd do absolutely nothing for him.

By everything you wrote I'm pretty sure you have tritanomaly.

You can do the color blind check test for Android to check your severity more precisely. Just tap on the colored squares as soon as you notice them, so as fast as you can.

And make sure you don't have any color/visual filters turned on on your device before doing that test.

Mild protanomaly or deuteranomaly should pass CP3. Try color blind check test for Android to check your severity.

Optometrist is not an eye doc and you definitely don't wanna visit them for a problem like this. What you need is an ophthalmologist. Don't get stressed, it might have something to do with you being nervous. We see colors in our brains afterall not in our eyes.

Hownold are you, have you been on any kind of medications or drugs recently? Did you have any head injury, accident, looked at bright intense light or anything similar? Have you tried any of the online colorblind tests? If not I suggest this test since it can evaluate your current color vision pretty accurately. Just make sure to turn all color/night filter off on your screen.

If you have android phone, you should do this test and report back your PDT, points, and severity score, so we can see what's your type and severity of deficiency.

You can additionally do red/green and tritan(blue) tests from this page.

There are plenty of causes for acquired color blindness. Depending on your type it can be anything from drugs side effects, looking at the strong UV/sunlight, to certain eye diseases.
