It is said in the śāstras that the head of the body represents the brāhmaṇas, the arms represent the kṣatriyas, the abdomen represents the vaiśyas, and the legs, beginning with the thighs, represent the śūdras. 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.
