Color is a social app for photos. You take photos and then the photos appear on the fly with other photos in your vicinity. You get to see the photos your friends are taking as well as other people within 100 feet of your photo. The app will group photos based on who your friends are so you are more likely to see photos that you are interested in. The service is available on Android or iPhone.
