Flaming Chrysoberyl
Flaming Chrysoberyl (#91B306) is a true yellow 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 (72°, 94%, 36%) places it in the highly saturated band at a mid 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
Old French flamme, flame — present-participle of flame. As a color modifier, flaming implies a saturated-and-fire-and-bright-color quality, the bright color of autumn-Maple-and-Oak deciduous-foliage fall-color and Yule-log fire emission. Sits at the bright-and-warm end of the grid, parallel to fiery and blazing in usage.
A beryllium-aluminum oxide gem — particularly the chartreuse-green variety distinguished from emerald by its different chemistry. Mined principally in Brazil, Sri Lanka, and Madagascar. The color refers to a faceted Brazilian chrysoberyl: a saturated, slightly cool yellow-green with the gem's signature high refractive index.
