The Multicolr Search Lab is a fantastic tool that does an excellent job of finding great images based on the colors you select.
Well, yes it is. Our multicolour search is actually quite unique. We of course have not invented colour search but we have done an amazing job of letting users select up to 10 colours to search for; we also spent a lot of time coming up with a clean yet awesome interface to display the search results and believe me when I say we are not doing simple histogram analysis for the colour search. It is Sunday evening so go on… go play and see for yourself.
