If you haven’t seen this Multicolr Search Lab tool yet, go there now. Like right now. A friend passed this tool on to the masses today re: Twitter, and I’ve spent at least an hour playing with the colors and images.

This is how it works - pull up the page via the link and click on a color in the palette to the right. The gray blocks on the left will fill with images from flickr that hold that color (monochromatic). Then, add up to nine more colors to find an image that will fit your color scheme. The colors are extracted from 10 million of the most “interesting” Creative Commons images on flickr, so that means that you actually can use the images that are revealed from you color choices.

Have fun!
