HueGo

HueGo allows users to sample colors from their display or from a color prism. HueGo can be made to float in front of other apps by selecting "Sampler is Global" from the "View" menu. Sample area is adjustable from 1 pixel to an 11x11 area. Easy to use, just open HueGo and press the escape key to begin sampling. Point to the color you want to sample and press escape again.
