FYI, those 8% of males / 0.5% females stats are not about complete colorblindness, so almost all of those people use color in their life

Yes for men mostly it’s red/green colorblindness. It’s one reason traffic lights have a uniform order and why you might get tested on which light means stop and not what color on a written test in the US.
