Color management is hard business. I think of myself as fairly savvy in this area, but it took me a long time to get the basics down. (I recommend Tim Grey’s Color Confidence and Fraser, et al’s Real World Color Management, 2nd ed., for those who want a quick introduction and a thorough grounding.)

People who implement a color-managed workflow — including photographers who print their own images — may be interested in the ICC_Users mailing list.
