If you mean he can see colors when there are no colors, I would definitely take him to an opthalmologist. It is good to have something like this looked into as soon as possible.
you mean its not the same color you see . or when he sees a stop light the colors are upside down some people see that and read differently too.But if its not the same color you see then see a Doctor about Brain and Eye Doctor Doheny eye clinic in U.S.C. Their The Best In The World.
I'm not sure what you're asking about either. It isn't clear what you're asking. Are you referring to color blindness, like he CAN'T distringuish the differences between certain colors, or are you referring to something he sees that is like a blur of colors that he CAN see?
Your question is not well written. Please try again. He can or can not see colors. What is he doing, what is he looking at?
