do you not see the color at all?
My red-green colorblind family member sees all pure red, green, and brown colors the same. Can't tell the difference at all. Once you get into the warm-reds or red-browns, he can see a difference and can usually guess what the color is.
For example, on a tree or plant with bright red flowers, he doesn't see a color difference. He can see the flowers only if he's up close enough to see the shape. When he was little, the way his mother found out he was red-green color blind was when he started coloring the grass in his pictures red. She asked, why are you making the grass that color? He answered, because that's the color it is.
At night, he's been known to stop at green lights. Can't see if it's red or green until he's up close. But I agree, it's really interesting! I wonder what they really see.....
