I am following my own suggestion that replies to postings must be
significantly shorter than the item being referred to. And this will be my
last posting on these various topics.

It is clear we come from very different schools of thoughts -- different
paradigms, if you will, and if paradigms differ, discussion is often
ineffective in resolving issues.
To me, color is real (hell, i even spell it differently). It is a
psychological perception and we understand most of the details of the
circuitry, how light energy at different frequencies (wavelengths) excite
the eye's receptors, how that gets transformed into an opponent-process,
and what the mapping is between the light array and the perception (taking
into account surface-surround effects (which are also well understood),
adaptation effects, corrections for "white" (too technical to cover here),
and so on. That identical light spectra can be perceived differently
depending upon the surround, prior exposures etc., is also well understood.
Color science is a real science, even if color is not in the physical
world, just the subjective one. Those bands of color in the rainbow are
really there in the mind, even if they are not in the spectrum. (we also
perceive brown and pink -- and those are not in any spectrum either).
That's my kind of psychology: understanding how subjective experiences
arise from physical stimulation. And why, although different cultures have
different color names -- and even claim they see fewer or more distinct
colors than we do, we understand how this happens.
Enough on this topic. You will disagree, so there is no need to write and
tell me. I already know -- and I bet everyone else on this list knows we
disagree about this. You are a materialist, and a behaviorist. Too bad: you
have my sympathies.
