Buttoned Shag Teal

Old French bouton, button — past-participle of button. As a color modifier, buttoned implies a clear-and-fastened-and-formal quality, the crisp color of Edwardian-period formal-attire fully-fastened-and-formally-dressed gentleman's-attire. Sits at the crisp-and-finished end of the grid, parallel to trim and pressed in usage.

Old Norse skagg, beard / rough-hair. As a color modifier, shag implies a rough-and-shaggy-hair-or-pile quality, the visual register of Mid-Century-Modern-and-1970s-shag-rug hand-tufted-and-rough-and-shaggy wool-and-yarn-and-pile Mid-Century-Modern-and-1970s shag-rug surfaces under Mid-Century-Modern-and-1970s shag-rug interior-decoration light. Sits at the modifier-and-texture end of the grid, parallel to fuzz and fluff 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.
