ORIGINAL: Termyn8or "Obviously his world has no red and green, but also no brown, no purple, no orange, no teal or turquoise." Not so sure about that. I think it's more that they can't distinguish, that red and green look the same. Brown is red and green so maybe they see both as brown. It also may differ from person to person. What I don't know is whether the problem is actually in the brain or the eyes. There is also IIRC blue-green color blindness which is much more rare. Even rarer is total color blindness where one actually sees the world in black and white. Thing is people don't even notice until they're told usually. There are tests. Actually color blindness is why the red light is always on the top and the green light is always on the bottom. There is also a protocol for those instances in which the traffic light is mounted horizontally, I THINK the red light is always on the left but I am not sure. When I had my TV shop I had a color blind customer. Sometimes I had TVs that had a bad picture tube and could not display the color correctly. He bought them and actually said they looked better to him sometimes, that the image was clearer. Go figure. But if the guy in the video is a dog, cool. He knows where to lick :-) T^T Did you actually look at the site I posted? There are pictures there that show how a color blind person sees the world. I wasn't talking out of my butt and wondering what the world looks like when you are color blind...I can see what it looks like by looking at the pictures that are posted there. In the pictures representing red/green color blindness there is no red, green, brown, purple, orange, teal, or turquoise. Please don't take my word for it, go look. What red/green color blind people see from our perspective is a world with black, white, gray, blue, yellow, and ochre. From their perspective it's just how they see, and yeah....a lot of them don't even know. They can identify colors by position and some other cues, but no....they don't see them the way most of us do. You wondered where color blindness comes from...its the absence or malfunction of certain color sensitive cone cells in the retina. So it originates in the eye, not the brain.
