Functional Tied Teal

Latin fūnctiō, performance — adjectival suffix -al. As a color modifier, functional implies a clear-and-purpose-fit-and-utilitarian quality, the crisp color of Mid-Century-Modern and Bauhaus form-follows-function design-aesthetic. Sits at the crisp-and-functional end of the grid, parallel to practical and utilitarian in usage.

Old English tīgan, to-tie or to-bind. As a color modifier, tied implies a hand-tied-and-knotted quality, the visual register of hand-tied-and-knotted-rope-and-string hand-tied-and-knotted-fishing-net-and-shoelace-and-bow hand-tied-and-knotted-rope-and-cord surfaces under hand-tied-and-knotted-rope-and-cord working-light. Sits at the modifier-and-texture end of the grid, parallel to sewn and knot 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.
