David,

Wow - those links are great! I've always wondered about HSL (Hue, Saturation, and Luminance), but had become so accustomed to thinking in RGB terms that I never pursued this topic any further. I'm beginning to get a feel for how one might use this type of info to create complementary color schemes for an application.

Thank you very much!
