its possible. e.g color blind people.
but if i and 20 other people looked at the same thing and got asked the color of it, it would 99.9% the same color

ZachLee wrote @UniqueHorizon - Yeah haha it's just a thought ;)

@Jelly_Bean - yes but our eyes could receive it differently and no one would ever notice because how can you see what color another person is seeing?

@trev57 - well yes I know that... that wasn't what I was trying to get at... -___-

So you are meaning like 'what if blue is really red but we just don't know?'

It wouldn't really matter, it all goes back to the names of colors simply just being words to an object or thing.

okay, first 'M NOT SAYING THIS IS TRUE. ITS JUST A THOUGHT.
what if, when I see "blue" shirt, you see "red" shirt. We would both call the color "blue" because that is what we would have been taught to call it.

im have a mission now... im going to get a bunch of people for raise money for this person to get help...

Different materials, objects and items have a different make up of atoms and electrons. Any object, by its nature, will, when exposed to light, do one of the following:

reflect or scatter light (reflection and scattering)
absorb light (absorption)
do nothing (transmission)
refract light (refraction)
