Hue, Saturation and Value question

[Garrett Hylltun]

Rev 2.6.1 / OS X

Greetings,

Does anyone know what the math equations are behind getting the 
Saturation and Value of a color?

Hmmmm, maybe I should elaborate more.

I have sliders setup for RGB, and I actually have figured out how to 
setup a slider for Hue, but I can't figure out how to code some sliders 
for Saturation and Value.

Does anyone have any info on this topic?


Thanks,
-Garrett
