Picture an ancient Greek craftsperson handling a dark blue mineral or a blue-glazed object: that was kyanos, the source of cyan. The word may reach even farther back to Mycenaean Greek ku-wa-no, written in the astonishing Linear B script centuries before the classical alphabet. Its ultimate origin is uncertain; one leading possibility connects it with a Hittite word for copper, a precious stone, or a copper-blue color, but the evidence is not solid enough to call the case closed. English first used cyan blue in 1879 and shortened it to cyan by 1889, giving printers and scientists a precise name for the color between blue and green. The same Greek color-stem also appears in cyanide, cyanobacteria, cyanosis, and kyanite—so a word that looks like a cheerful computer color carries echoes of minerals, chemistry, and medical blueness.
