Aristocratic Celery

#1c9b00
Notes

Aristocratic Celery (#1C9B00) is a deep green 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 (109°, 100%, 30%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Aristocratic
adjective

Greek aristokratía, rule by the best — adjectival suffix -ic. As a color modifier, aristocratic implies a saturated-and-noble-and-hereditary quality, the deep-rich color of pre-modern European aristocracy hereditary-class livery-and-armorial-bearings. Sits at the bold-and-aristocratic end of the grid, parallel to patrician and lordly.

Celery
noun

Apium graveolens, the marsh herb cultivated for its crisp pale-green stalks since at least the time of Homer, though the modern crunchy celery is a nineteenth-century selection. The color refers to a fresh celery rib in profile: a soft, slightly muted pale green with the optical translucency of high-water-content vegetable tissue. Lighter than pear, cooler than wheat.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
