A nifty ZopeProduct to ease color management. It generates secondary colors from a primary color, using standard color theory. This is especially useful for designers. See also ColorzSkin.
The Colorz product is also an interactive tutor of color theory :-) You can try it out just because it is fun to play with colors.
