Chivalrous Roller

#0a8c3b
Notes

Chivalrous Roller (#0A8C3B) 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 (143°, 87%, 29%) 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 magenta. 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.

Roller
noun

The family Coraciidae — Old World rollers whose acrobatic flight gives the family its name. Coracias caudatus (lilac-breasted roller) of southern Africa displays saturated turquoise wing covers. The color refers to a male lilac-breasted roller's wing: a saturated, slightly cool deep turquoise.
