This colorscheme was originally forked from the "Darcula" colorscheme (alem0lars/vim-colorscheme-darcula)[http://github.com/alem0lars/vim-colorscheme-darcula].
The colors were not quite right in 256-color terminals, so I tweaked them to my liking.
Add this Plugin line to .vimrc:
call vundle#begin()
...
Plugin 'thecodesmith/vim-colorscheme-codesmith'
...
call vundle#end()
