Authoritative Persimmon

#c66a0d
Notes

Authoritative Persimmon (#C66A0D) is a true orange with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (30°, 88%, 41%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Authoritative
adjective

Latin auctōritāt-, authority — adjectival suffix -ive. As a color modifier, authoritative implies a saturated-and-formal-imperative quality where the hue carries decisional weight and institutional credibility. Sits at the bold-and-authoritative end of the grid, parallel to commanding and magisterial in usage.

Persimmon
noun

Diospyros kaki, the East Asian persimmon — a fruit eaten ripe from the tree in Japan since at least the eighth century, where its color is named kaki-iro. The fall color of the unblemished astringent fruit: a dense, slightly red orange with the velvet finish of a wax-skinned Hachiya. Closer to maple syrup than to citrus, with the patient warmth of a fruit that takes a hard frost to sweeten.

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.
