Picture a Bronze Age Greek craftsperson handling a vivid blue material—perhaps copper carbonate, perhaps lapis lazuli, perhaps something traded under the name ku-wa-no. By the time the word appears as Ancient Greek κύανος, it could describe dark blue, blue enamel, or the precious stone itself. Its deeper ancestry is a small historical mystery: one theory connects it with Hittite kuwannan-, associated with copper and a blue shade, while another treats it as a non-Indo-European borrowing. English first used cyan blue in 1879 and shortened it to cyan by 1889, long before screens made the color familiar through printing and digital color systems. So cyan carries a tiny archaeological puzzle in its name: every modern pixel may echo a Bronze Age blue whose exact identity has been lost.
