I'm looking for some procedures (or better yet, some formulas) for converting
between RGB format like all the Windows APIs use and Hue/Saturation/Luminosity
and vice versa.

The Windows 3.0 color control panel allows users to design custom colors 
(under Color Palette) using either/both formats.  I would like to do a similar
thing in my application.

Does anyone know how or have pointers to books that might discuss it?  I've
checked Petzold's 2nd edition and Peter Norton's new Windows book, but no
dice.

Thanks in advance,
