"a tool for checking foreground and background color combinations of all DOM elements and determining if they provide sufficient contrast when viewed by someone having color deficits. All the tests are based on the algorithms suggested by the World Wide Web Consortium (W3C)."

"We extracted the colours from 10 million of the most “interesting” Creative Commons images on Flickr. Using our visual similarity technology you can navigate the collection by colour." Very cool if you add several colors to the mix.

great for obscure names too. rose madder. burnt umber. caput mortuum (death's head). papaya whip. smalt. zinnwaldite (the color of corporate america).
