I know the feeling!! (see my recent *erroneous* post about what I thought was a
problem in POV's v3.7.1 beta 4.)

Your second image (with the mostly-black business card example) clarified
something for me. I originally thought that your upper-right color histogram was
supposed to be showing not only the color components of the example, but the
*amount* of each color as well. (I.e., I was wondering why the amount of pure
black occupied such a tiny area at the center apex of the histogram.) But I
think I see now that the histogram only represents the colors themselves, not
the color amounts.

I was thinking: To show the amount of each color, perhaps your lower-right
discretised view of the colors could be composed of actual 3-D cylinders-- the
longer the cylinder, the more of that color in the example being worked with.
(The 'black cylinder' there looks kind of 3-D anyway-- jutting out in -z -- so
perhaps you've already thought of this. The other colors don't show that(?), at
least as far as I can tell. Perhaps exaggerating the 'length' of all the color
cylinders there might help, in that regard.) Anyway, just an idea.
