It would be futile. You can't prove that we all see colors the same way to begin with.
My red could be your purple and we'd never know. |
This entire post is false. We have empirically defined the entire color spectrum.

How so, by placing it on the spectrum and claiming red is 620-750nm wide? Maybe by studying brain functions when someone contemplates a color? How much does that tell you what red actually is? Or do you understand the feeling of thrill by studying a molecule of adrenaline and how it physiologically alters the body upon being released into the bloodstream? Nope, you cannot... you need to empirically experience it otherwise you are missing the point here. This kind of information that can only originate from our senses - quale - are one of the strongest arguments for empirism as opposed to rationalism. You can see why this would bother a lot of people and the reason sometimes just cast it aside or dismiss it.
That's why it was so hard to discover daltonism; where people usually perceive the entire spectrum as being shades of yellow and blue. How could you possibly now something was wrong when that's all you ever knew? In fact the only thing those tests do is try to trick people into not seeing a clear pattern of two different colors - to us - among what they perceive as different colors but are actually different tonalities of the same color. It must have taken Dalton a hell of a philosophical effort to realize his rainbow was "different shades of yellow and blue" as himself put it.

If you open a crayon box and it says Red, are you suggesting that the majority of people don't see the same Red?
