Our minds perceive color possibly in our own unique way. It is possible I see blue as you see red. There is absolutely no way to explain what a color looks like. Try to imagine a new primary color. It is impossible, its like trying to explain blue to a blind man that's never seen a color before. For all we know, I could say "Hey I love that shade of purple" when you could be seeing orange. Color is a quale, about 8% of men and 1% of women have some form of color impairment and they don't even know.
