This is forked from https://github.com/fugalh/desert.vim
The only change I needed to make was to change the diff colors. The original settings sometimes had text match its background when vimdiff'ing shell scripts.
In the picture below, the top screenshot is the "before" image, and the bottom one is the "after" image.
Put in ~/.vim/colors or (\vimfiles\colors on Windows) and do
:colorscheme desert in vim to use.
You can download it from the command line like so:
$ curl -LSso ~/.vim/colors/desert.vim \ https://raw.githubusercontent.com/dblume/desert.vim/master/desert.vim
