ColorSnapper 1.6

Check out a colour picker assistant for Mac devices and screens. Work with a toolset for capturing, copying, recognizing, and extracting information about the colour of any object, area, and even individual pixel on the display. Use several hotkeys to simplify operations.

ColorSnapper — the missing color picker for OS X.
ColorSnapper is an easy-to-use tool for quickly finding out the color of any pixel on the screen. It is activated via a configurable system-wide hotkey, giving you a magnifying loupe to easily pick the pixel you need. The resulting color is copied to clipboard in a format of your preference.
