Glaukos
The gleaming grey-green color of the sea and the owl's eye — a color term that blurred the boundary between grey, green, and blue, associated with divine sight and sea-light.
The Meaning of Glaukos
Glaukos presents one of the most discussed puzzles in Greek color perception: the ancient Greeks did not organize color the way moderns do, and glaukos — applied to the sea, to Athena's eyes (glaukopis), to olive trees, to honey — covered a range that modern languages split between grey, green, blue, and silver. The owl was glaukos-eyed, giving Athena the epithet glaukopis (owl-eyed or gleaming-eyed), connecting divine sight with the particular quality of light reflected from still water or polished metal. The sea was glaukos in its calmer, gleaming aspect, distinct from the wine-dark (oinops) sea in storm. As a mythological figure, Glaukos was the name of several figures: a sea-deity who had eaten a divine herb and become immortal; a Lycian hero in the Iliad; and the son of Sisyphus who was devoured by his own mares. The color and the figures shared something: the quality of shimmering, liminal, between-world light.

Fun Fact
Homeric Greek had no single word for blue — the sky is described as bronze, the sea as wine-dark or gleaming — and glaukos covered much of what we now call blue-grey, suggesting ancient color categories were organized around brightness and sheen rather than hue.
