Genopal Pro

GenoPal Pro is an easy to use, but hard to beat, color combination and matching tool. The colors generated are based on human-perceptual technology, and produces natural and harmonious color schemes unlike conventional Color Wheel software. It lets the user pick a color from an existing palette or any window or picture on your computer.
GenoPal will move around in over 16 million different colors, to find the ones that suit your taste.
