Functional Tufted 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 French touffe, tuft. As a color modifier, tufted implies a hand-tufted-and-puffed quality, the visual register of Edwardian-and-Belle-Époque-tufted-upholstery hand-tufted-and-puffed-and-upholstered velvet-and-silk-and-leather tufted-and-puffed-upholstery surfaces under Edwardian-and-Belle-Époque hand-tufted-upholstery-and-cushion light. Sits at the modifier-and-texture end of the grid, parallel to fluff and flock 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.
