Four Comparisons Used For Krishna’s Complexion

“The shyama color is not exactly blackish. Shrila Bhaktisiddhanta Sarasvati Thakura compares it to the color of the atasi flower. It is not that Lord Krishna Himself appears in a blackish color in all the Dvapara-yugas. In other Dvapara-yugas, previous to Lord Krishna's appearance, the Supreme Lord appeared in a greenish body by His own personal expansion. This is mentioned in the Vishnu Purana, Hari-vamsha and Mahabharata.” (Shrila Prabhupada, Chaitanya Charitamrita, Madhya 20.337, Purport)
