Antiseptic Rime Lagoon

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 English hrīm, hoar-frost-on-twigs. As a color modifier, rime implies a feathered-frost-and-fog-deposited quality, the visual register of Scottish-Highland-and-Cairngorm-rime hand-feathered-frost-and-fog-deposited Scottish-Highland-and-Cairngorm-rime-and-Pennine-cap rime-and-feathered-frost-and-fog-deposited surfaces under Scottish-Highland-and-Cairngorm-rime-and-Pennine-cap Cairngorm-Highlands-and-Scottish-Munro-and-Pennine-cap freezing-fog-light. Sits at the modifier-and-weather end of the grid, parallel to hoar and sleet in usage.

A shallow body of saltwater partially or fully enclosed by a barrier — coral atoll lagoons in the Pacific, Venice's Laguna Veneta, the Florida Keys' backcountry. The color refers to the average reflectance of a calm tropical lagoon at midday: a saturated, slightly muted blue-green with the optical clarity of shallow water over white sand. Brighter than reef, cooler than aquamarine, with the postcard weight of a Pacific atoll seen from above.
