I hated learning colors when I was a kid. Green traffic lights look white. I’ve painted the sky purple more than once in art class.
I’m a moderate deutan — meaning I have a form of red-green color perception deficiency. You can see what it looks like here.
Enchroma sells glasses that are supposed to help a color blind person see more colors. To say I was skeptical when I first heard about it would be an understatement. Well, now I have a pair, and see for yourself my reaction.
