Most colorblind people are so-called "anamolous trichromats" who have 3 functioning color channels, but one or more has some kind of deficiency. Instead of being completely unable to distinguish UI elements, they might simply take longer at it, or more likely to spend 10 extra minutes hunting for the red key the boss dropped in the grass.
Yep, exactly. I know cardinals are red and they look obviously red to me. Hard as hell for me to spot one in a tree though, this was the first sign when I was a kid. "What do you mean you can't see it!?"

Does it mean that trees also look reddish to you?
I don't understand how cardinals can look "obviously red" and still blend in with the foliage, which average people would consider "obviously green". My mental model for red-green color blindness is that most reds and most greens are hard to tell apart because they largely look like shades of yellow.

That's more subtle to test.

I still remember by my surprise somewhere around age 15 when I learned that other people could tell a dead tree from a live one just be color.
