Spacegray is a colorscheme for Vim loosely modeled after the spacegray theme for Xcode.
Here are a few screenshots of Spacegray:
If you don't have a preferred installation method, I recommend installing pathogen.vim, and then simply copy and paste:
cd ~/.vim/bundle && git clone git://github.com/ajh17/Spacegray.vim.git
Then in your ~/.vimrc, add this line:
colorscheme spacegray
If you use Spacegray inside a Terminal, please make sure you use a Terminal with 256 color support.
The image below contains the Spacegray palette. You can use a color picker to use the colors for your Terminal:
