PIXELATION is pretty good. Circle icons and dark/black mode. Not too black though. Still provides a lot of color for icons.

Yeah, I downloaded it a few days ago to answer some questions and decided to run it for a bit since it finally exited beta.
Also, the icon pack is Pixelation
Pixelation recently got updated with the colorful google icons and is in general very complete.

The icon pack I used is Pixelation Icons. The camera icon in the bottom right is custom made by me and the wallpaper is one of Google's live wallpapers.
Edit: The weather widget is made with Zooper and I'm using action launcher 3.

Thanks. Pixelation is the icon pack. I made the camera icon myself because I couldn't find one I liked.

The navigation buttons are Nova actions with icons from the pack you may have to select manually.

This one is a mix of what you want (colored circle, black inside) and the opposite (black circle, colored inside)
