cramoisi

borrowed (13th c.) via Spanish carmesi from Arabic قرمز qirmiz (kermes, a Mediterranean insect from which a deep red dye was obtained), ultimately derived from Sanskrit कृमिज, kṛmija, a compound of कृमि, kṛ́mi ('worm') and ज, ja ('made from, produced by'), thus meaning 'red pigment produced by a worm'.
