With painters--and many other picture-makers, we so often are talking about
value when we are talking about light (and dark), so that is what I was
thinking in terms of here.  But, of course, no light waves, no color.  In
the case where the gentleman was refering to the ink colors on the print
(dye in this case, probably instead of pigment) I'm used to people using
the term color to simply be designating hue, rather than understanding that
color in pigment is made up of hue, temperature, value and intensity.  And
the color appears however it does because of how the light waves hitting
the pigment--or dye or ink or other material accepts (absorbs) or rejects
certain light waves.

So I agree with you.  And also, in terms of what I was taking the gentleman
to be meaning and how I was using 'light'--in terms of discussing the
actual 'color' material rather than the light waves hitting it, I also
stand by what I said--and I certainly may have mistaken his intention in
his 'light' reference.

Bruce, as I've said before, I always thoroughly enjoy and appreciate your
comments on things and am so pleased you are sharing with us!  Thanks!
