Brimming Bracken

#39920a
Notes

Brimming Bracken (#39920A) 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 (99°, 87%, 31%) 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

Brimming
adjective

Old English brymme, brim / edge — present-participle of brim. As a color modifier, brimming implies a saturated-and-overflowing quality where the hue spills past the edge of its visual container with rich pigmentation. Sits at the bold-and-saturated end of the grid, parallel to replete and abundant.

Bracken
noun

Pteridium aquilinum, the cosmopolitan bracken fern — one of the most widespread plants on Earth, dominating the understory of British and European deciduous woodland. Bracken color refers to mature bracken fronds in summer: a saturated, slightly muted deep yellow-green with the matte finish of large pinnate fern.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
