佛說觀佛三昧海經 3.37

3.37

釋子眾中五百釋子，見佛色身猶如炭人；比丘眾中有一千人，見佛色身如赤土人；優婆塞眾中有十六人，見佛色身如黑象脚；優婆夷眾中二十四人，見佛身色猶如聚墨。如是四眾各各異見。比丘尼眾中有比丘尼，見佛色身如白銀色；優婆夷眾中有優婆夷，見佛色身如藍染青色，如是四眾觀佛色身所見不同。

Among the assembly of Śākya sons, five hundred Śākya sons saw the Buddha's form-body as like a person made of charcoal; among the assembly of monks, one thousand people saw the Buddha's form-body as like a person of red earth; among the assembly of upāsakas, sixteen people saw the Buddha's form-body as like the leg of a black elephant; among the assembly of upāsikās, twenty-four people saw the Buddha's bodily form as like a heap of ink. Thus the four assemblies each saw differently. Among the assembly of bhikṣuṇīs, there were bhikṣuṇīs who saw the Buddha's form-body as white silver in color; among the assembly of upāsikās, there were upāsikās who saw the Buddha's form-body as indigo-dyed blue. Thus what the four assemblies saw when contemplating the Buddha's form-body was not the same.
