Adobe.vim is a project mainly written in Vim Script, it's free.
Adobe theme, easy on eyes. Coloring philosophy inside.

Great for many programming languages, especially Python. Also cursory testing of bash, perl, html, vim, java, c++, moin, and mutt. Includes console coloring to match GUI colors (for tested cases, please let me know of ones I missed).
