You brought it up, so... I believe humans have three different cones in their eyes, these cones pick up what we understand as the "three base colors". Color blindness is when a person is missing one of these cones. Anyways... I've heard that some females (like maybe two) actually have four different types of cones, this is to say they can pick up four different base colors, so colors would match differently to them. Now let me disclaim, I actually know nothing about what I just wrote besides what I remember reading somewhere on the internet (if it's on the internet, it's got to be true!).. but thought I'd share as it is just fun information.

My theory is this (once again, this theory is coming from someone who knows nothing about the topic, but just likes to think about stuff), I've heard people say the same thing but not using base colors, for example "I wonder if their yellow is my blue", to which I think would be wrong as the same colors would no longer match to everyone.. but perhaps if all the base colors were rotated? I dont know.. aren't some base colors darker then others? If so I'd think the above "matching" would apply, if not perhaps it's possible.

Like I said, all the above is coming from someone who knows nothing about anything he just said.. I just like to think about stuff. Perhaps someone who knows something could shed some light on this?

When you see red, what's really going on is that part of your eye is being stimulated by a wavelength somewhere around 630nm (I don't remember what pure red is, but it's near there). All your life your brain has been receiving the same signal when that wavelength hits your eye. When your were young, adults said to you "That is red." You didn't decide one day what red was, you learned it from others. Therefore, it's entirely possible that your brain processes the 630nm wavelength differently than mine does. If I were able to look through your eyes, I may be shocked. The way our brains interpret data is something we know very little about, so I think it's entirely possible that we all see the same color differently.
