No I was just trying to point out a problem with mixing 
reflection_amount & co with colors in the tentative pseudocode. POV-Ray 
certainly has no need to normalize colors.

Thinking about it the easiest way would be to define all the amounts as 
colors with all components between 0 and 1, and run the algorithm for 
each color, rather than trying to treat all colors simultaneously...
