CamColor!

Elegant tool for detecting color names. Simply aim your phone's camera at the target object and you will see the name of the color.

The ColorVisor detects colors in your environment by using the cameras that are built into your device. Additionally, the app supports scanning colors in photos and images. ColorVisor identifies the color’s name and its components in RGB and HSB. If you like the color, you can store it, add notes, fine-tune the color component values, or even change the color name.
