Hermetic Color Picker

From Hermetic Systems:

Hermetic Color Picker allows you select a color visually and then get the red, green and blue components, expressed either as decimal, hexadecimal or as RGB values, which can then be copied to the clipboard for pasting elsewhere. The color of each pixel on your monitor is composed of individual red, green and blue colors. Each of these components can have an intensity measured on a scale of 0 through 255. Thus the number of possible pixel colors is 256*256*256 = 16,777,216 (although studies of retinal cone cell sensitivities indicate that humans can actually distinguish no more than about a million colors). The RGB color model can be imagined as a cube in Cartesian space, with each coordinate ranging from 0 through 255.
