Is pink just light red? Think about it. If you mix blue and white together you get light blue. If you mix green and white together you get light green. If you mix orange and white together you get light orange. But if you mix red and white together you get... pink? But pink doesn't really look like light red, it just looks sort of pink. Is it a cultural thing, or do we maybe distinguish pink because that's the color of infected skin, and we're naturally selected to pay special attention to it? What are your thoughts on this?
