This is faster version of onedark.vim. I've replaced all complicated checks and function calls with simple list of execute highlight group-name colors. Original onedark is sourced about 40 ms on my old laptop. This version needs only 7 ms. Of course, I had to sacrifice something. My version doesn't have 16 color terminals support, italics is always on and you can't override colors settings from your vimrc.
There is only one option. Use it if you don't want transparent background.
