I began modifying the finish definitions of the standard metals.inc. The
pigment were right to me, but they looked really too dark with the new
finishes. So I normalized every color vector ( < r, g, b > / vlength (< r,
g, b > ) ) and then I multiplied it by sqrt(3) in order to get every color
vector as bright as <1,1,1> ( if a normalized vector is one unit long and
you multiply it by sqrt (3) you have a color vector as long (i.e. bright) as
<1,1,1> since vlength (<1,1,1>) = sqrt ( 1^2 + 1^2 + 1^2) = sqrt (3)). Then
I lowered each value to get the right brightness. Here follow some (badly
compressed :-\ ) examples. As an aside, if you want the whole .inc file
just ask.
Cheers,
