That's for sure.  More obvious than not matching the EM spectrum was the way the
sample colors were produced.  At high sampling levels it kind of fudged towards
white but in most cases everything had a tendency to look a bit orange.  This can be
seen in the image of the sphere.  I hope 3.5 took care of this problem.

The macro than Nathan included for creating light color maps is the same one used to
create dispersion n_elems in the dispersion patch if I remember right.  The point of
having the color_map for the light was so you could create colors that look a little
better than the macro could create.

Doubt if anyone remembers, but I created that image of the sphere to serve as the
slash screen to my windows compile of Daren's dispersion patch.
