cyan

Origin

Learned borrowing from Ancient Greek κύανος (kúanos), a shade of blue variously described as similar to cornflower, copper carbonate, and lapis lazuli, Mycenaean Greek 𐀓𐀷𐀜 (ku-wa-no), possibly from Hittite [script needed] (kuwannan-, “a precious stone; copper; shade of blue”) - likely from Kuwanniya, all going back to kuwanna (woman), related to "queen" and γυνή. Compare modern Greek κυανός (kyanós), also used for cyan.
