Let me re-word that, so it hopefully makes better sense...

Given:
radiosity{brightness 1.0}
light_source{rgb .7}
object{... pigment{rgb <.3,.5,.7> finish{diffuse 1.0}}

Does the 'automatic balancing' keep the object surface's DIFFUSE color from
exceeding .7*<.3,.5,.7> (as if NO radiosity is used)--depending of course on the
angle-of-incidence of the light source hitting the object? Or does my diffuse
setting need to be manually reduced, to keep the color from washing out to, say,

       .7*<.3 + 1.0,.5 + 1.0,.7 + 1.0>  or maybe  (1.0 + .7)*<.3,.5,.7>

....DUE TO THE ADDITION OF RADIOSITY LIGHT. Or am I still clueless about what
'automatic balancing' means? :-O
