See the paper in the SPIE proceedings (and several other places)
 about ~1980 by Steve Pizer of the Univ. of North Carolina on
generating good color scales. He basically does a psychophysics
experiment for each user and determine thes optimal color scale for
each user + monitor combination. It turns out that this gives the
highest amount of image transfer per pixel - as you have measured the
just-noticeable color difference for the image chain in question.

He has been doing these sorts of measurements for more than a decade -
so you might want to contact him: smp@cs.unc.edu
