Antiseptic Frock Moss

#235e45
Notes

Antiseptic Frock Moss (#235E45) is a deep teal with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (155°, 46%, 25%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Antiseptic
adjective

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.

Frock
modifier

Old French froc, monk's-habit-or-loose-garment. As a color modifier, frock implies a monk's-habit-and-pinafore-and-day-frock quality, the visual register of Benedictine-monk's-frock-and-Edwardian-day-frock hand-monk's-habit-and-pinafore-and-day-frock Benedictine-monk's-frock-and-Edwardian-day-frock-and-pinafore frock-and-monk's-habit-and-pinafore surfaces under Benedictine-monk's-frock-and-Edwardian-day-frock-and-pinafore Cluny-Abbey-and-Edwardian-tea-room habit-and-day-dress-light. Sits at the modifier-and-textile end of the grid, parallel to gown and cope in usage.

Moss
noun

Bryophyta — the nonvascular plants that colonized land 470 million years ago, before vascular plants and far before flowers. The color refers to a thick mat of Hypnum or sphagnum on a temperate forest floor: a soft, slightly yellow-shifted green with the velvet texture of millimeter-scale leaves. Dustier than fern, deeper than lichen, with the slow patience of a plant that lives by absorbing rain through its surface.
