For the benefit of your eyes, you can use this to randomize the color schemes available.

Installation

Basic install - very simple (*nix or cygwin install)

mkdir ~/.vim
git clone https://github.com/jinfan/vim-randcolor.git ~/.vim

if you use vim + pathogen

cd ~/.vim
git submodule add https://github.com/jinfan/vim-randcolor.git bundle/vim-randcolor

if you use vim + vundle

" add to .vimrc
Plugin 'jinfan/vim-randcolor'
:PluginInstall

if you aren't using any of these, then you should:)

Using

To change the colorscheme of Vim, add to your .vimrc with this suggested key mapping:

nnoremap <leader>c :RandColorScheme<CR>

Then you can push the combined key and let your eyes enjoy the different colors.

Please note that the current color scheme will be displayed in the command line.

Recommendation

I strongly encourage you to install more color scheme from flazz/vim-colorschemes.
