I was thinking about how the word 'fair' was used to describe positive things--and also a person of light skin and hair color. Now--I am NOT saying that people with light skin and hair color ARE "better"; but it has been evidenced in many ways that people perceive this quality as more desirable. My question is: how did light come to be associated with positives: the fair-haired boy; light on one's feet; a light cake, or biscuits; walk in the light; clothed in white occurs all through the Bible; even on TV shows, the good guy is nearly always dressed in lighter colors than other characters.
