The color of something is the color of the spectrum that isn't taken in by an object. However when I look at the color "green", do I see the same tint someone sees when they see "blue"? The identification of a color is what we've been told, and we've essentially been told what colors don't go good together. So how do we know that all of our eyes see the same thing? -Samantha B.
