I like the idea behind http://contrastrebellion.com/, and plan to implement that on my websites.
However, I'm a developer, not designer. I read a lot about the subject -where I must build the combination- but wonder where I can find great looking and proven combinations with dark & light backgrounds.
I try looking at some websites, but suspect the visual on them distort my ability to judge what exactly I'm looking for (I like it because is good contrast or because the site look good to me?).
