I don't know how it works, but I have it - I can see red and green and pink in big blobs, but when there's lots of small red and green (or pink) details mixed - they seem the same to me (if their darkness is similar). Also I have problems with big uniform colour areas it there's small amount of green mixed with pink or red and vice-versa. I was making a sunset skybox for a game, and friends were wondering why the sky is slightly green - for me it was pinkish-red-yellow, but I put there some green by mistake.
