I wonder if all people see colors the same way. With the obvious exception of the color-blind and those who can't see at all, we generally take for granted that we all see the same colors. But what if what I see as green, you see as red? We both agree that grass is usually green but is it my green or yours? Early on in life we learn what to call the colors that we see. At this point, children learn that the tree trunk is brown, that car is red, and the sky is blue. We could however, be calling these things the same color but actually be seeing them differently. Just imagine what the world would be like if you saw each color as a different one. Maybe that's how some people see the world as normal.
