又優婆夷淨行經云。佛告毘舍佉。如來有六種光明。何謂為六。一青光。二黃光。三赤光。四白光五紅光。六紫光。光色照明。是名如來六種光明。

The Upāsikā-śuddhacaryā-sūtra also states: The Buddha told Viśākhā: 'The Tathāgata has six kinds of radiance. What are the six? First, blue-green light; second, yellow light; third, red light; fourth, white light; fifth, pink light; sixth, purple light. These colours of light illuminate, and are called the six kinds of radiance of the Tathāgata.'
