I'll use the term "perceptual colormap" to refer to any colormap in which the luminance has been controlled, with an eye towards properties of the human visual system.

One easy way to create perceptual colormaps is to work in a device-independent colorspace, one in which luminance is a seperate axis, and then convert to a calibrated monitor. On a CRT, this means that we know the chromaticity coordinates each of the red, green, and blue phosphors, and we know their relative luminances.

And that would be wonderful. But I would bet that most people in this room don't have calibrated monitors, though we might reaonably assume that calibrated monitors would be necessary for correctly generating perceptual colormaps. Our paper shows that by exploiting known results from perceptual psychology, a calibrated monitor is not in fact necessary.

First I need to nail down some terminology, and then talk about previous work.
