For the benefit of your eyes, you can use this to randomize the color schemes available.
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:)
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.
I strongly encourage you to install more color scheme from flazz/vim-colorschemes.
