In much of New Spain, the mixed-race children of Spanish men and Indian women, known as mestizos, outnumbered Indians; an intricate caste system marked gradations of skin color, mixtures of Europeans, Native Americans, and Africans, as if skin color were like dyes made of plants, the yellow of sassafras, the red of beets, the black of carob. Later, the English would recognize only black and white, a fantasy of stark and impossible difference, of nights without twilight and days without dawns.
