Functional Jetty 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 jetée, thrown-out / projection. As a color modifier, jetty implies a stone-or-timber-projection quality, the visual register of Cornish-fishing-village small stone-and-timber-built sea-jetty fishing-and-boat-loading surfaces under Cornish-fishing-village granite-and-cobble harbor working-light. Sits at the modifier-and-place end of the grid, parallel to pier and quay 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.
