I was responding to your earlier comment on the paint and fabric industries and the responses were a bit of a side thread to what some of the real life issues with colour match are all about. As I had a lot of experience in one of these industries and some limited experience in the other. While not specifically mentioned, there are similar issues in the printing industry and the Pantone Matching System (owned by x-Rite, just as Gretag-MacBeth and Munsell) is the industry standard here. This is not the publishing industry per se, but product packaging as well.
