This is my vim colorscheme file. It's basically just a copy of Molokai with some tweaks.
I parked it here mainly for ease of managing with vundle but you're certainly free to use it if you wish.
If you prefer working with a dark backgrounded colorscheme, Molokai is a great looking, easy to read, and really comprehensive set that can be used either as is or as a good base to start from if you want to customize it.
