Hey there! I made an app called CSBW for this. It's a search bar widget that you place on your home screen and you can change the appearance of it in CSBW settings.
Awesome! You can use Custom ICS:

And here are the hex codes:
Green: 16ff42
Classic Green: 1aff7e
Amber: ffce53
Blue: 03e7ff
It's part of Poweramp, a music player app I've used since my S4. Parts of the UI, namely the notification widget, simply do not function properly on my Pixel 2 XL unfortunately, so I'm looking for alternatives that I like.
I'm just so used to Poweramp, it's though to make the jump. I don't stream, I have gigs and gigs of MP3s, so the search is a daunting one.

I'm not sure, as I don't have an S7, but in most devices, you need root along with an app like ifont, substratum or gravity box to change the font. Looks like iFont works with some Galaxy devices. Worth a shot!
Some free fonts that are available are monofonto and overseer.
I know this is an older thread, but have you tried TeslaUnread? It's an unread badge counter for Nova launcher that should work with all of your installed apps. You can find it here: https://play.google.com/store/apps/details?id=com.teslacoilsw.notifier
For PipTec Green, when you place the widget on your home screen, it will give you color options.
If you mean changing the vault droid to the boy, you can download that widget here: https://play.google.com/store/apps/details?id=com.natewren.crippledbatterywidget
