Gaudy Bracken

#51ac48
Notes

Gaudy Bracken (#51AC48) is a true green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (115°, 41%, 48%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Gaudy
adjective

Middle English gaude, trick / showy ornament — adjectival suffix -y. As a color modifier, gaudy implies a saturated-and-cheaply-bright-and-overdone quality, the bright color of carnival-and-fairground novelty-attraction painted-and-lit decoration. Sits at the bright-and-flamboyant end of the grid, parallel to garish and lurid in usage.

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.
