Cone is a beautifully designed iOS app that uses the phone’s camera to pick Pantone colors from the world around you.

The $2.49 app samples colors along with their Pantone name in real-time. Cone is a very handy way to create satisfying color palettes from real life scenes, and it also provides the hex color values for use in web or unlimited graphic design.

I don’t know that I have a use for this app but it’s a very clever implementation.
