I don't think that you'll need complex math for this. In MegaPov source
code there is function (RGBtoHue in color.c)from MSGTracer, which
converts RGB to visible spectra (although part of it is commented out,
but You can get idea). Basically you should convert RGB to hue, then
convert hue to frequency (or wave length).
