[Canto 10, Ch. 8]
transcendental bodies according to the different  yugas ;  śuklaḥ —sometimes white;  raktaḥ —sometimes red;  tathā —as well as;  pītaḥ —sometimes yellow;  idānīm kṛṣṇatām gataḥ —at the present moment He has assumed a blackish color.
TRANSLATION
Your son Kṛṣṇa appears as an incarnation in every millennium. In the past, He assumed three different colors—white, red and yellow—and now He has appeared in a blackish color. [In another Dvāpara-yuga, He appeared (as Lord Rāmacandra) in the color of śuka, a parrot. All such incarnations have now assembled in Kṛṣṇa.]
PURPORT
Partially explaining the position of Lord Kṛṣṇa and partially covering the facts, Gargamuni indicated, “Your son is a great personality, and He can change the color of His body in different ages.” The word  gṛhṇataḥ  indicates that Kṛṣṇa is free to make His choice. In other words, He is the Supreme Personality of Godhead and may therefore do whatever He desires. In Vedic literature the different colors assumed by the Personality of Godhead in different millenniums are stated, and therefore when Gargamuni said, “Your son has assumed these colors,” he indirectly said, “He is the Supreme Personality of Godhead.” Because of Kamsa’s atrocities, Gargamuni tried to avoid disclosing this fact, but he indirectly informed Nanda Mahārāja that Kṛṣṇa, his son, was the Supreme Personality of Godhead.
It may be noted that Śrīla Jīva Gosvāmī, in his book  Krama-sandarbha , has enunciated the purport of this verse. In every millennium, Kṛṣṇa appears in a different form, either as white, red or yellow, but this time He personally appeared in His original, blackish form and, as predicted by Gargamuni, exhibited the power of Nārāyaṇa. Because in this form the Supreme Personality of Godhead exhibits Himself fully, His name is Śrī Kṛṣṇa, the all-attractive.
Factually, Kṛṣṇa is the source of all  avatāras , and therefore all the different features of the different  avatāras  are present in Kṛṣṇa. When Kṛṣṇa incarnates, all the features of other incarnations are already pres-
