Mischna zu Wajikra 18:19

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.
