Google Images is great for finding pictures of anything and everything — you can even check out millions of historic Time magazine photos — but what if you want to search for images by color?
We already know that Yahoo has a shop by color application that comes in handy when you're looking for an article of clothing in a particular color, but if you want to do a general color search for any object, that's when Google comes in handy.
All you have to do is tweak the search results for the URL.
For this search, I typed http://images.google.com/images?q=laptop&imgcolor=orange. Where it says laptop, just change to whatever item you are looking for and where it says orange you can replace with any color you'd like!
