From the developer:
ColorSnap allows you to use the camera in an iPhone to capture real world colors and match them to the Sherwin-Williams paint color palette. With ColorSnap, it's easy to take color inspiration from a photo in your library or one you just snapped. Then choose matching colors or Ask Sherwin-Williams for recommendations. Either way, it's a cinch to match, adjust, and save colors.
