Antiseptic Iceberg

#1eccdb
Notes

Antiseptic Iceberg (#1ECCDB) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (185°, 76%, 49%) places it in the highly saturated band at a mid 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 red. 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.

Iceberg
noun

Floating freshwater ice — calved from glaciers and ice shelves — characterized by the saturated pale blue of the underwater portion. The blue comes from the same Rayleigh scattering that colors the sky, intensified through compressed glacier ice. The color refers to a freshly calved Antarctic iceberg's underwater face: a saturated, slightly cool pale blue.

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.
