No you don't. ;-) For the visually oriented such as myself - an RGB gamut is triangular; a CMYK gamut is an irregular rough hexagon which doesn't cover the corners of the triangle but pokes out a bit round the middle of each side of the triangle. The human visual gamut is a tongue shaped thing with a flat base, and completely covers both the tiangle, the hexagon, and a bunch of space not covered by either. -- Chris Lilley, W3C [ http://www.w3.org/ ] Graphics and Fonts Guy The World Wide Web Consortium http://www.w3.org/people/chris/ INRIA, Projet W3C chris@w3.org 2004 Rt des Lucioles / BP 93 +33 (0)4 93 65 79 87 06902 Sophia Antipolis Cedex, France
