I've created a few dark color themes recently for myself and people at work. Most, is not all, of the contexts are implemented. There are also matching iTerm themes in there.
Feel free to clone my git repo or grab the master zip. Screenshots are in the README.md
I don't mind suggestions either because it takes a while to create a theme from scratch and sometimes I get lazy. If you see something glaringly annoying or wrong with one of themes, please create an issue an I will fix it ASAP.
