You are actually asking for two things (in Sublime jargon):
* A theme, which styles the widgets: tabs, sidebar, panels, etc..
* A color scheme, which styles the text window. These, confusingly, come in .tmTheme files. (I should note that what precisely gets highlighted is determined by syntaxes, which come in .tmLanguage files. But that's another story.)
FWIW, this is the color scheme I use:
It's designed for writing rather than coding, but I have been using it for both tasks for over a year now (with minor tweaks) and I can attest that your eyes will not fall out of their sockets. (Although I do use f.lux/redshift.) The syntax closely mirrors the Monokai (the default ST2 theme). If you're interested, I will be packaging it with some non-intrusive Markdown stuff over the weekend.
The theme in the screenshot is Soda Light. Probably not contrasting enough.
Hope this helps,
