Bountiful Fiddlehead
Bountiful Fiddlehead (#1D9F27) is a true 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 (125°, 69%, 37%) 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
Old French bonté, goodness — adjectival suffix -ful. As a color modifier, bountiful implies a saturated-and-generous-and-abundant quality where the hue offers visual richness without measure. Sits at the bold-and-saturated end of the grid, parallel to abundant and plentiful in usage.
The tightly coiled emerging frond of any fern — particularly the edible fiddleheads of Matteuccia struthiopteris (ostrich fern), eaten as a foraged spring delicacy in New England. Fiddlehead color refers to a fresh-emerged fern fiddlehead: a saturated, slightly cool yellow-green with the satin finish of curled new growth.
