Sure, and I think we probably agree that some reform is needed around trademarking colors. So I'll correct myself as well and agree that it is a problem -- though somewhat limited in scope. My point was only that it isn't a broad limitation such as Copyright creates that spills over into say, letting a camera take pictures with a shade of blue or using blue in a piece of software. I believe the scope of the trademark's application is fairly narrow, so it's not something most people in other fields need to worry about.
