Untroubled Greek Teal

Latin turbāre, to disturb — negative-prefix un- plus past-participle of trouble. As a color modifier, untroubled implies a clear-and-calm-and-undisturbed quality where the hue carries no visual agitation. Sits at the crisp-and-calm end of the grid, parallel to serene and placid in usage.

Latin Graecus, of-Greece. As a color modifier, greek implies a classical-and-marble-and-blue-sea quality, the visual register of Athens-and-Aegean classical-Hellenic temple-and-pottery hand-built marble-and-sea-blue surfaces under Greek-Aegean classical-temple Mediterranean light. Sits at the modifier-and-cultural end of the grid, parallel to roman and hellenic 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.
