The DesignMaster Color Calculator is probably the best color picker I've ever played with! Not only does it tell you the RGB, CMYK and HTML color values, but it also allows you to save that info to the built-in clipboard, making it easy to copy and paste into other applications or code. It also gives you a nifty color wheel that shows you complimentary colors and a number of other harmonious color schemes. There's nothing to install, and of course, it's free.
While you're there, take a moment to look at the free templates, contracts and tutorials DesignMaster Training has to offer.
