cramoisi

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