Hello everyone ! 
I’ve created a colorscheme with “one” accent color, greys and terminal attributes : dabruin.kak
It’s heavily inspired by vim-bruin, and I truly think it has allowed me to concentrate more and retrieve information quicker. Plus, high contrast themes are always a good idea for your eyes.
The idea was to have sane defaults that can be used directly, but let the user customize their accent color through a kakoune option
Default colors scores high, in this contrast checker at least

I’ve written an article about why I wrote dabruin.kak and what made me change from everforest to a minimal colorscheme (i only talk about me ahahah).
