Thank you all for your help and advice.. I'm new to POVRay (and raytracing,
actually..), and it's not always easy to understand tuning...

Anyway, I tried the various tricks you all gave me, and, finally, I have the
feeling that the most realsitic, in my case, was to put a multiplier on
colors statements (like 'rgb 2').

I appreciate your help and look forward being able to help you, too.
