Double clic on any proifle on the Mac, and Colorsync utility will come up and allow you to inspect the profile in 3D. It can also compare several profiles in 3D. There is not much point in doing 2D gamut comparisons, is my belief. Various other tools, free and non-free to do this are floating around the web, of which the most powerful is probably Steve Upton's ColorThink which runs on Mac and Windows. http://www2.chromix.com/colorthink/ Edmund
