I'm no expert, but I thought the black and white thing originates really from night and day. It is easier to see when there is light (often perceived as white) than it is at night (often perceived as black). We used white and black to convey the color of the sky. A white color reflects light while a black color absorbs light. This is how I've always thought about it. I never associated this with skin color until someone told me. I still have never internalized this because it just doesn't make sense to me.

I'm open to being wrong but to be this connection of archetypal meanings and skin color is a stretch. I don't look at a white phone or black phone and think good or bad (in fact I have a black phone and prefer dark colors while my skin tone is the opposite). One which requires a lot of fundamental change in language and how we think. Because I'm sure I'm not the only one that has codified this representation in my mind. And most of us should understand archetypes are not how you go about judging the world or people. I don't see a person dressed in red and think "angry" (which would be a different emotion in a different culture), or yellow and "happy". I just see colors.

That is pretty different to me.
