"하양과 검정은 색깔입니다."
Translation:White and black are colors.
Black and white are colors depending on which color theory you follow. One is by famous German physicist Manfred Richter: The German term for it is "unbunt" bzw. "Unbunte Farben". Which literally translates to "Non-colorful colors". He argues that if the only difference between a strong brown and a light orange is the amount of black/white in there, then can't the same be said about two greys? Pushing that to the extreme makes black and white colors just like any other form of grey IN THAT THEORY. Please not that other theories say different things and there's rarely a right or wrong, just a different way of calling/describing things.
