Princely Lemongrass

#509800
Notes

Princely Lemongrass (#509800) is a deep 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 (88°, 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Princely
adjective

Latin prīnceps, first / chief — adjectival suffix -ly. As a color modifier, princely implies a saturated-and-royal-secondary quality, the deep-rich color of European crown-prince coronet-and-livery vestment. Sits at the bold-and-aristocratic end of the grid, parallel to lordly and regal in usage.

Lemongrass
noun

Cymbopogon citratus, the tropical grass whose lemon-scented stalks flavor Southeast Asian curries, Thai soups, and herbal teas. The color refers to a fresh-cut lemongrass stalk in cross-section: a saturated, slightly yellow yellow-green with the matte finish of fresh grass-family fiber.
