It was my understanding that there's a bunch of different versions of color-blindness, some people can't see a difference between blue and green, and others really do see all gray. As far as color goes, I really do think everyone interprets it differently. I'm addicted to watching decorating shows, and I've noticed that no matter what color paint is used, everyone refers to it by a different name, ie an orangish color can be everything from rust to red depending on who looks at it. Of course, interpreting color doesn't help when everyone can adjust the settings on their monitor (or tv screen). Lin
