Thanks. The red-to-yellow colorbar is already on the image -- I don't
create it. The map of gradient values to the 3D colorspace would have
to be determined from this colorbar, which also has errors in it
(garbage in, as Dr. Fanning says.) I suppose this would be an
irregular grid of gradient values within the 3D colorspace.

Basically, there's a color-coded image with a colorbar *on* the
image. The colors, even those in the bar, often have errors because
they were digitized from analog tape recordings. Still, it is
possible to eyeball the images to determine color levels. I want the
computer to do something more quantitative than the eyeball analysis.
