The Multicolr (yes, they spell it that way) Search Lab is an extremely cool image search engine that uses colors instead of search terms to find images. You can select up to 10 different colors (or pick the same color more than once to emphasize that color) and the program searches through 10 million creative commons licensed images on Flickr to find images with those colors. If you find one you like, you can just click on it and you’ll be taken to the original Flickr image. It’s a lot of fun mixing odd colors to see what is found – the images are often quite striking too. The Multicolr Search Lab is provided by idée and they also have a couple of other interesting search pages on their site, but the Multicolr one is the most fun in my opinion.
