Hygienic Pater Teal

Greek hygieinós, healthful — derived from Hygieia (goddess of health). As a color modifier, hygienic implies a clear-and-medical-clean quality, the crisp color of Mid-Century-Modern clinical-and-hospital interior-architecture surfaces. Sits at the crisp-and-clean end of the grid, parallel to sanitary and sterile in usage.

Latin pater, father. As a color modifier, pater implies a Latin-father-and-paterfamilias-and-Pater-Noster quality, the visual register of Pater-Noster-and-Roman-paterfamilias hand-Latin-father-and-paterfamilias-and-Pater-Noster Pater-Noster-and-Roman-paterfamilias-and-Catholic-prayer pater-and-Latin-father surfaces under Pater-Noster-and-Roman-paterfamilias-and-Catholic-prayer Roman-Senate-and-Catholic-liturgy paterfamilias-light. Sits at the modifier-and-Latin end of the grid, parallel to mater and dux 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.
