Note
The theme served me well, but I was getting tired of vimscript. An overhaul can be found at mxi/vampire.nvim.
My tuned colorscheme for ultimate productivity.
I tried a lot of black/white/grayscale colorschemes. Most of them seemed to be designed by CS:GO players because you need to flashbang gamma correct your eyes to be able to see the contrast between different highlight groups (by far the biggest problem being the comments which are damn near impossible to read with a lot of schemes.)
