Google has recently added a great addition to their image search. Well I think it is a nice little addition..

“The option that lets you filter images by the predominant color has been added to Google Image Search’s interface. Just click on “All colors” above the search results and you can choose one of the 12 available colors.” – Google Blog

Of all the advanced options in the image search, this has to be the most practical… now I can find all the red WRX’s!
