Stable Wave Teal

Latin stabilis, standing-firm — sharing root with stand. As a color modifier, stable implies a clear-and-firm-and-unchanging quality where the hue carries the visual register of resistant-to-modulation-and-fade pigmentation. Sits at the crisp-and-firm end of the grid, parallel to steady and settled in usage.

Old English wagian, to move to and fro. As a color modifier, wave implies a periodic-and-rolling quality, the visual register of Pacific-and-Atlantic mid-ocean wind-driven rolling-swell-and-foam mid-distance horizon surfaces under open sky. Sits at the modifier-and-place end of the grid, parallel to surge and tide 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.
