I grew up color blind. I have the red and green color blindness. I recently read that Brad Pitt has face blindness. where the rest of the world around you is normal but you can't remember anyone's face.
You think that would make difficult to act because you would have a hard time knowing who you are talking to. I guess you would have to remember people's voices verses faces. I still sometimes have trouble with reds and browns and yellows and greens.
that makes since. It took me a little longer to learn colors in the red and green spectrum. I still have a little trouble at times though.
