SB Canto 4

The śūdras are sometimes called black, or kṛṣṇa. The brāhmaṇas are called śukla, or white, and the kṣatriyas and the vaiśyas are a mixture of black and white. However, those who are extraordinarily white are said to have skin produced out of white leprosy. It may be concluded that white or a golden hue is the color of the higher caste, and black is the complexion of the śūdras.
