Mishnayos Negaim Perek 1 Mishnah 2

הפתוך שבשלג (the variegation of the snow-white leprosy) – that is mixed in the white color and red substance that is in the בהרת/discoloration/bright white spot on the skin that it appears as an intensely bright spot sparkling like snow. כיין המזוג בשלג (like the red wine mixed with the snow – before the latter is dissolved) – for its whiteness is greater and its redness is less.

הפתוך שבסיד ההיכל – that which is combined in the plague which is like the lime of the Temple, appears. כדם המזוג בחלב – for the redness that is in it is greater. And even though it (i.e., the Mishnah) doesn’t teach פתוך/the variegation other than with the בהרת /discoloration and its derivatives or subcategories, the same law applies for there is also variegation in the שאת/swelling and its derivatives or subcategories, as it is taught in Torat Kohanim (i.e., the Sifra) (Leviticus 13:10): “a white swelling [on the /skin]/שאת לבנה [which has turned some hair white],” (see also Leviticus 13:19), it teaches that it defiles part of it. [The phrase] "בהרת לבנה אדמדמת"/a white discoloration/bright spot on the skin streaked with red (Leviticus 13:19), teaches that it defiles with variegation. From where [do we learn] to give that which is stated of this one and with that one (i.e., wine mixed with in snow and blood mixed in milk – describing the variegation of the lime in the Temple)? The inference teaches us (Leviticus 13:9): "נגע צרעת"/When a person has a scaly affection.

שבזה ושבזה – that is in the snow and in the lime [of the Temple].

דיהה (is fainter) – it is missing from the whiteness, which is not bright/resplendent in its whiteness like it. And the Halakha is according to Rabbi Akiba.
