Your code doesn't have to look so sour. I've collected a list of Xcode themes (and fonts) a while ago. Many more themes have been submitted in the meanwhile so if you have a theme you'd like to add to the list, just let me know!

One of the few light themes that made the list.
Inspired by the famous Railscast TextMate theme.
Available for all kind of editors on GitHub.
Nice dark variant.
My absolute favorite!
Bitstream Vera Sans (download)
Consolas (instructions to download on Mac)

Thanks for the tip Damian Carrillo.
Droid Sans Mono (download)
Inconsolata (download)
My favorite. Shipped with Mac OS.

A great Menlo alternative that comes with three different line height options. Recommended if you prefer a little bit of air between your lines.
Great font, also shipped with Mac OS.

Adobe's open source font. Recommended!
