Multicolr for Flickr

One of the cooler tools on the photo-sharing website Flickr involves being able to sort photos by "Most Interesting," a category that takes a photo's composition, subject and color usage to set visually interesting photos apart from bland ones.

Multicolr Search Lab is an auxiliary tool that searches photos Flickr deems interesting by colors. Users select shades from a palette on the right side of the page, clicking the same shade multiple times to increase its intensity. As you can see from the images in the gallery, the tool is astonishingly powerful.
