Take a look at this very cool photography site run by Nikki Farquharson called Random Got Beautiful. She has pages with different colors assigned to them and photos of those various colors. Her idea is to take photos that are dominated by a single color and place them with others so as to make a whole new concept. It is open for public submission. I submitted my swings photo a while back for the blue page. If you click on blue and scroll down a bit you can see it.
