I've been looking for a formual to convert a single value to an RGB value. I've found several on converting a RGB value to a single value (most have to do with color to gray scale conversion). I'm trying to map single values to the color spectrum. Hence, zero would equal white (255, 255, 255). Does a formula exist? Thanks.

Are you looking for something like a light frequency to RGB map? I don't know of any purely algebraical formulas off the top of my head. Maybe some form of interpolated lookup table?
