Thanks, Marek and Michael. It seems like you're approaching closer to something like the three-dimensional calibration I was saying we need for tricolor gum, but lots easier than what I was imagining.
In the meantime I had an idea that helped me understand my problem: I made a copy of the greyscale inverted red (cyan) channel, added a color layer to it, then turned that back into greyscale and looked at it side by side with the original greyscale. That visual sxs helped me grasp the relationship between negative color and tonality (uncomplicated by curves) better than weeks of staring at numbers and curves and calibration charts, and I'm a number person, for heavens' sake.
