Unwavering Broccoli

#399800
Notes

Unwavering Broccoli (#399800) 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 (98°, 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

Unwavering
adjective

Old English un- (negation) plus wafrian (to flicker). As a color modifier, unwavering implies a saturated-and-constant quality where the hue maintains its full strength without flicker or shift. Sits at the bold-and-firm end of the grid, parallel to steadfast and firm in usage.

Broccoli
noun

Brassica oleracea var. italica — the Italian-bred cabbage variety eaten for its tight green flower clusters, named from the Italian broccolo (cabbage sprout). Broccoli color refers to a fresh raw broccoli crown on a cutting board: a saturated, slightly cool deep green with the matte finish of dense green florets.
