Antiseptic Cloak Teal

Greek anti- (against) plus sēptikós (putrefying) — adjectival suffix -ic. As a color modifier, antiseptic implies a clear-and-disinfected-and-clinical quality, the crisp color of medical-laboratory and operating-theater hand-scrub-and-sanitizer surfaces. Sits at the crisp-and-clean end of the grid, parallel to sterile and sanitary in usage.

Old Northern French cloque, bell-or-cape. As a color modifier, cloak implies a heavy-shoulder-mantle-and-bell-shaped quality, the visual register of Anglo-Saxon-and-medieval-cloak hand-heavy-shoulder-mantle-and-bell-shaped Anglo-Saxon-and-medieval-cloak-and-pilgrim-cloak cloak-and-heavy-shoulder-mantle surfaces under Anglo-Saxon-and-medieval-cloak-and-pilgrim-cloak Canterbury-and-Compostela-pilgrimage wool-cloak-light. Sits at the modifier-and-textile end of the grid, parallel to cape and cowl 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.
