Here's the theme I use. It's simple, clean and colourful. It's wide, too, because I like to see instant results from, say, Wolfram or Google Translate.
Enough detail without being cluttered. If you want it more subtle, just make it grey and thinner. But then it wouldn't be lime, would it?
I hope you enjoy!
