#3> The magic number to remember is the "Just Noticeable Difference" (JND). For dE00, JND is around 2.0. Below that, people struggle to tell two colours apart. Below 1.0, basically no one can.
Except for a tetrachromat. Specifically, a strong tetrachromat that has both four colour channels in the brain and a different frequency on the fourth cone.
Who are, admittedly, hella rare. Apparently there are less than a few dozen confirmed world-wide.
But they do exist.

Computer screens have three-dimensional color spaces. Tetrachromacy doesn't change that.

I'm color blind, and not even a little bit, but I scored 0.0084. I've noticed before that my perception of contrast is slightly better (than that of the people I ever compared it with; admitteldly, that's only a handful, but they weren't colorblind).

Is that so? Our color perception is weird. It's one dimension split in three overlapping sectors. Adding a fourth sector may add information that makes it easier to distinguish colors.
