論云「若於青瘀等，作意思惟，於顯色貪令心清淨。若於變赤作意思惟，於形色貪令心清淨」。述曰：貪白紅顯色，以青瘀等對治。於形色起長短方圓等貪，以除去皮肉對治。若小乘云變赤相者，死屍初青後赤，變作赤血身，以除形色貪。大乘解：先皮肉等色赤，除去皮肉形色，名變赤也，即變者赤也。

The treatise says: "If one attends to and contemplates lividity and the like, one purifies the mind regarding greed for varṇa-rūpa. If one attends to and contemplates turning red, one purifies the mind regarding greed for saṃsthāna-rūpa." The commentary states: Greed for the colors white and red is countered by lividity and the like. Greed arising toward saṃsthāna-rūpa such as long, short, square, or round is countered by removing the skin and flesh. In the Hīnayāna explanation of the characteristic of turning red, a corpse is initially livid and later red, turning into a body of red blood to eliminate greed for shape. The Mahāyāna explains: First, the color of skin, flesh, and so forth is red, and removing the shape of the skin and flesh is called "turning red"—that is, what transforms is red.
