Antiseptic Tawny

#a66a1d
Notes

Antiseptic Tawny (#A66A1D) is a true orange 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 (34°, 70%, 38%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary azure. 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.

Tawny
noun

From the Old French tané, tanned — originally the brown of leather tanned with oak bark. The color now describes the gold-brown of a lion's coat, the autumn flank of a fox, the ground color of a tawny owl. Warmer than wheat, more saturated than tan, with the animal-fur warmth of a word that almost always describes living things rather than objects.
