Chivalrous Arugula

#668a10
Notes

Chivalrous Arugula (#668A10) 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 (78°, 79%, 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

Chivalrous
adjective

Old French chevaleros, knightly — adjectival suffix -ous, derived from cheval (horse). As a color modifier, chivalrous implies a saturated-and-knightly-and-gallant quality, the deep-rich color of medieval-Romance chanson-de-geste hero-and-troubadour song tradition. Sits at the bold-and-chivalrous end of the grid, parallel to gallant and knightly.

Arugula
noun

Eruca vesicaria, the Mediterranean mustard-family green — peppery and bitter, eaten as rocket in British English and rucola in Italian. Arugula color refers to fresh wild arugula leaves: a saturated, slightly muted deep yellow-green with the matte finish of small notched leaves.
