Patrician Celery
Patrician Celery (#509A17) is a true lime 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 (94°, 74%, 35%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin patrīcius, of the noble class — derived from pater (father). As a color modifier, patrician implies a saturated-and-aristocratic-and-Roman-Republic quality, the deep-rich color of Roman-Patrician-class toga and senatorial-livery hereditary-aristocratic dress. Sits at the bold-and-aristocratic end of the grid, parallel to senatorial and imperial.
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.
