Hello,

I'd like to create a 256 color map for Fractint 17.2 which very closely
represents the visible spectrum (~0.38 to 0.71 microns) - one could call it
a rainbow.  What I plan to do is to divide the wavelength range of visible
light into 255 discrete points (may not be evenly spaced), and then determine
the color mapping parameters for each particular wavelength.

The question:  how do I convert a particular wavelength in the visible range
to the three RGB .map parameters for use by Fractint?

Of course, if somebody's already done this, then I'd like to get the map, but
I'd like to know how to do it anywhoze.

Jon

and I'll send you some information.  It WILL be worth the inquiry, I think.
