Idée Labs, a company that makes a suite of reverse image search tools, has a really cool demo of its Tineye MulticolorEngine. This is a tool that allows you to search 20 million Flickr Creative Commons images by color! The technology demonstration is fun and addictive: It takes this sample set of 20 million images and allows you to search for images whose palettes contain up to five colors in the relative percentages you choose.

Below are some samples of searches we performed. The first image is the baseline tag "flowers" with no color choices. We then clicked some color(s) to narrow the search. Amazing!
