Srimad-Bhagavatam Lectures

Akṛṣṇa means not black. So "not black" means you can accept any other color which is not black. So that there is proof in the śāstra that Lord, Kṛṣṇa, has also many colors.

Lecture on SB 1.16.11 -- Los Angeles, January 8, 1974:

So Śrī Caitanya Mahāprabhu is predicted in the Śrīmad-Bhāgavatam and other scriptures as the Supreme Personality of Godhead. We do not accept Śrī Caitanya Mahāprabhu simply because He was a saintly person. There is controversy about Śrī Caitanya Mahāprabhu amongst the Vaiṣṇava community. Just like the Nimbārka Sampradāya. They say that "We accept Śrī Caitanya Mahāprabhu as a great devotee," but we, Gauḍīya Sampradāya, we say that Śrī Caitanya Mahāprabhu is the Supreme Personality of Godhead, because it is stated in the śāstra. Kṛṣṇa-varṇaṁ tviṣākṛṣṇam (SB 11.5.32). He is Kṛṣṇa, in the category of Kṛṣṇa, kṛṣṇa-varṇa... Just like brāhmaṇa-varṇa. Kṛṣṇa-varṇa, same category. But He is, by complexion, yellowish, not kṛṣṇa. Tviṣā akṛṣṇa. Tviṣā means "by the bodily skin." Just like we have different color, different skin, different color, similarly, tviṣā, by His skin, He is not kṛṣṇa, He is not black. Tviṣā akṛṣṇa. Akṛṣṇa means not black. So "not black" means you can accept any other color which is not black. So that there is proof in the śāstra that Lord, Kṛṣṇa, has also many colors. Śuklo raktas tathā pītaḥ. When, similarly, when Kṛṣṇa's horoscope was made by Gargamuni, he said that "This child formerly had śuklo raktas tathā pītaḥ. He was white color, He was yellow color, and He was red color." So this pītaḥ, yellow color, is also Kṛṣṇa's another color. Kṛṣṇa-varṇaṁ tviṣākṛṣṇam. So here, tviṣākṛṣṇa. Akṛṣṇa means not black. So "not black" means you must take the other three, namely white, red, and pīta. So other two colors in the Satya-yuga and Dvāpara-yuga, was manifested, red color and white color. Hayagrīva, white color. So the pīta..., kṛṣṇa color is also finished. Therefore pīta, yellowish color.
