Chabad.org — Chumash, English translation + Rashi for Vayikra 13:31
Torah Temimah cites Sifra (Toras Kohanim) for the inclusion of green and red hair in the relevant hair assessment.
Sifra — Vayikra 13, Midrash Sefer
English: Although the verse specifies black hair, the broader word “hair” includes green and red hair as well for this assessment.
Textual derivation
The Sifra reads the general word “hair” to include green and red hairs in this assessment, despite the verse’s earlier specific mention of black hair.
