I have been uncertain for some time about how to improve the presentation of the gaumt plots produced by ColorThink. Two-dimensional plots of profiles can give a misleading view of the relative size of two colour spaces. Links to the current 2D plots are listed below, but a more valuable 3D display can be found at Dry Creek Photo. I'd lilke to be able to offer a simialr service, but I don't know if I can afford (or master) the required technology.
