I definitely think you have a better vocabulary than me. red blindness=protanopia.
But I don't believe I have color deficit.
If you look at the pictures in Yellowman's post a few back, they look black and white to me.
Maybe a little not bright white, but definitely not beige or brown, but dark black.
OK, I'll take off-white and dark black.
The picture in Yellowman's post is accurate.
Well... His picture is of a painted XL, so it doesn't count
OK. I looked again, how about slightly grey.
Well, I see I lose in other opinions.
Now a little more. Here's a picture. Clearly shows a little brown.
