It’s supposed to solve the dilemma of winding up with all those cans of paint in colors that are too bold, too dingy, or not quite right. Both Benjamin Moore's Ben Color Capture and Sherwin-Williams' ColorSnap applications for the iPhone work the same way: Take a picture with your iPhone, zoom in on an area of color that you want to match in paint. Click “match” and the application gives you a range of paint options just like a real paint strip from their catalogue (either Moore or Sherwin). On the plus side, it shows the color’s nearest neighbors, in both lighter and darker shades.
