Thank you all.
I am almost done with what I need to do.

I attach an image of what I've done so far.
my only question is this one:
You can notice that the thumb has three tones of red.

The most "redish" part has RGB value (165,0,0)
However the material I assign to it has diffuse and ambient color (255,0,0)

How can I render it and keep the (255,0,0) value?

Thank you in advance,

Paul
