佛說觀佛三昧海經 3.58

3.58

The nuns saw the Buddha as silver-colored. Rising from their seats and baring their right shoulders, they paid homage to the Buddha and said: "Bhagavat! The Tathāgata now expounds the color of his body himself, which eliminates the immeasurable grave transgressions of sentient beings. For what reason have we, from the time we went forth from household life until this very day, seen the Buddha as silver-colored, with silver flowers, silver light, and all his ornaments entirely of silver? Why do we not see the radiant golden light of the Tathāgata, nor see the retribution merits of the Buddha's thirty-two primary marks?"
