Antiseptic Loggia Ocean

#056f91
Notes

Antiseptic Loggia Ocean (#056F91) is a deep cyan with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (195°, 93%, 29%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary orange. 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.

Loggia
modifier

Italian loggia, roofed-open-gallery. As a color modifier, loggia implies an Italian-and-Mediterranean-roofed-open-gallery quality, the visual register of Italian-Renaissance-and-Mediterranean-loggia hand-built roofed-open-gallery loggia-and-arcade-and-pergola architectural surfaces under Italian-Renaissance-and-Mediterranean loggia-arcade afternoon light. Sits at the modifier-and-architecture end of the grid, parallel to atrium and stoa in usage.

Ocean
noun

The body of saltwater that covers seventy percent of Earth's surface — a single connected mass divided by convention into Atlantic, Pacific, Indian, Southern, and Arctic. The color refers to the average reflectance of mid-depth temperate ocean: a saturated, slightly green-shifted deep blue with the optical depth of a body of water that absorbs all light below the photic zone. Deeper than mediterranean, cooler than peacock.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
