This is from the same book ("Billmeyer and Saltzman's Principles of Color
Technology", Third Edition, Wiley & Sons, 2000), on page 130:
"[W]e want to stress that color inconstancy applies to a SINGLE SAMPLE
[author's emphasis -- MU] viewed under multiple illuminants. 'Metamerism'
should never be used when describing a single sample's change in color due
to changes in illumination. Metamerism always describes the color
relationship between a PAIR OF SAMPLES [author's emphasis -- MU], at
minimum."
Like I said earlier, there's little to add to this one either. Couldn't be
clearer and more straightforward.
But of course anyone is free to ignore it.
