Serviceable Luna Teal

Latin servītium, service — adjectival suffix -able. As a color modifier, serviceable implies a clear-and-fit-for-purpose-and-durable quality where the hue carries the visual register of long-lasting-and-functional everyday-use design. Sits at the crisp-and-functional end of the grid, parallel to practical and utilitarian in usage.

Anas crecca, the small dabbling duck whose male in breeding plumage sports a chestnut head crossed by a glossy green-blue stripe. The color refers to that stripe — the iridescent panel just behind the eye: a saturated, slightly muted blue-green with the optical depth of structural color rather than pigment. Cooler than cypress, warmer than cerulean, with the ornithological specificity of a color named for one feather of one bird.
