Kyanos#00F4FF, a cool brilliant turquoise

At a glanceKyanos is #00F4FF, oklch(87.9% 0.150 200.6), a cool brilliant turquoise, fully saturated at the sRGB gamut edge for its hue. Pair it with a warm bold scarlet #C94F3C as an accent, a cool brilliant blue #5097E0 for harmony, and a cool faded blue #BCC9CA as a neutral. Reach for it as a screen-first brand or accent color, and it takes black text at AA contrast. It shifts further on press than a run can hold, though, so Rhapsody would keep it off print-led brand work.

The name

Why is it called Kyanos?

Kyanos's meaning, origin, and pronunciation, with sources.

Anchor: A35 · one of the 72 anchor hues of ART

Origin: Greek, written down since the Bronze Age, and probably borrowed even then from a lost earlier language

Meaning: Dark-blue enamel and lapis lazuli; the ancestor of cyan

Word: κύανος (Ancient Greek)

KEE-ah-noss (ancient) · /ˈkyː.a.nos/ (modern Greek stresses the end: kya-NOSS)

Mycenaean Greek ku-wa-no, pressed into clay tablets at Pylos in the thirteenth century BCE → Ancient Greek kúanos → Latin cyanus → English cyan, coined in the printing era.

In Homer, kyanos is the dark-blue enamel decorating Agamemnon's armor. In Theophrastus it is lapis lazuli. For a long time the word named a luxury material rather than a color in the abstract.

It was probably borrowed in the first place from some language spoken in Greece before Greek, possibly related to a Hittite word for a blue stone, which would mean even Greek borrowed its blue. All of which gives kyanos one of the longest continuous paper trails of any color word on Earth: written in three scripts across more than three thousand years, from Bronze Age palace inventories to the C in CMYK, the cyan cartridge in your printer.

LSJ s.v. κύανος; Wiktionary s.v. cyan, κυανός (Mycenaean, Hittite comparison); etymonline s.v. cyan. Dictionary + scholarly sources; no native-speaker review.
