I have to admit that there's still a little problem with my rainbows. In nature
you hardly can see ones with such soft colors; They indeed are a bit brighter.
Especially the blue band appears too blurred to me. This is because I wrote
some functions by myself to approximate the CIE visible light spectrum. I've
also tried the original values without approximation, but there I did something
wrong, the rainbow showed up 'out of color'. Instead of white, it was ugly
yellowish :)
But one day I will sit down in front of my PC and will begin to write a
brandnew, much better code for the color spectrum.

Greetings, Flo
