The Interface Hall of Shame (http://www.iarchitect.com/shame.htm) warns about any sort of hard-coded colors for a couple of reasons: 1) in other cultures, peoples' mental color associations are different and 2) some people have different types of color-blindness. That site has a lot to say about many aspects of interface design. Under the section about pointless error messages, you'll find a strange one that vfp3 gave me some time ago.

I thought of sending them this thread and inviting comment. That doesn't mean that they are "the interface police".
