You are right about that. I just did a test with *extreme* values for the three
rgb color functions -- like <60,0,0> (!) , and of course compensated my
finish{ambient...} value-- and I don't see any visual difference at all when
compared to using <1,0,0>.

Thanks for putting my erroneous 'clipping' thought to rest, once and for all.

Yes, that makes sense. No fiddling with the finish{...} values are required.
