Thread: Is red really red ?

My two eyes don't see colors exactly the same way. They both see red as red, but slightly different variations of it. I don't think people ever have completely the same perception of a light wave, but because of the rods and cones similarities people have (as Howie pointed out), I don't think any person sees red the way another person sees yellow. If that does happen, there is no way we can know because they will both call it the same thing.

interesting i often wondre of this myself

I can do that pretty easily, I think it is because one side of your brain is telling you to say the word, and the other side is telling you to say the color

I've pondered that too. What if red houses are really yellow? What if green plants are really black? Oh no, no one can be sure.
