I've come to the conclusion that people simply don't all perceive colors the same way (ignoring the factor of color-blindness). My wife and I have disagreements about whether two objects are the same or different colors. And given that people don't all see the same thing in the first place, it's no wonder there's confusion about exactly what to name things. 8-(
Part of that might be that some people have a structural difference in the retina so that they have four colours of cone cells instead of three (I don't remember whether this is a strictly sex-linked trait, or merely more common in women than in men).

Also things can look very different depending on the light source... can look the same in sunlight and different in fluorescent light, etc.
