It’s not a theory. It’s actual color science . Black doesn’t reflect light. It absorbs all of light, which is why you get hotter when wearing black material.

So the identification with the word black to reflect a skin color is incorrect,
because black isn’t even a color. Black and white are representations of light wavelengths being absorbed or reflected.

Why accept a name that we didn’t create, and was used to degrade us , and the
term isn’t a reflection of color?

It’s truly illogical.
