Vim colorschemes
vibrantink.vim
Very well-suited for editing Ruby (or Python) source files. Based on John Lam's rudimentary Vim version of Justin Palmer's VibrantInk color scheme for TextMate. This scheme also works on 256 color terminals.
Downloaded over 2000 times from vim.org and packaged in Ubuntu since Ubuntu 7.10 (Gutsy).
jo.vim
This is a colorscheme for Vim I wrote a few years ago (in August 2004 to be exact). It is licensed under the GPL (which is a bit useless for a color scheme, but seemed cool at the time). I got some feedback about it, apparantly it looks quite similar to the color scheme of IntelliJ. So if that is what you're looking for, be my guest and give it a try.
