וְאֶל־אִשָּׁ֖ה בְּנִדַּ֣ת טֻמְאָתָ֑הּ לֹ֣א תִקְרַ֔ב לְגַלּ֖וֹת עֶרְוָתָֽהּ׃
너는 여인이 경도로 불결할 동안에 그에게 가까이하여 그 하체를 범치 말지니라
Mishnah Negaim
The variegation of the snow-like whiteness is like wine mixed with snow. The variegation of the lime-like whiteness is like blood mixed with milk, the words of Rabbi Ishmael. Rabbi Akiva says: the reddishness in either of them is like wine mixed with water, only that in the snow-like whiteness the color is bright while in that of lime-like whiteness it is duller.
