Bold Swoop Forest

#1a8d2f
Notes

Bold Swoop Forest (#1A8D2F) is a deep 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 (131°, 69%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bold
adjective

Old English beald, brave, courageous — a quality word that crossed over to color in the late seventeenth century. Bold describes a color that asserts itself: high saturation combined with mid lightness, where the hue presents itself without compromise. Sits at the center of the bold-bucket grid, near strong and rich. Closer to a presence word than a pigment word.

Swoop
modifier

Old English swāpan, to-sweep-down. As a color modifier, swoop implies a fast-descending-and-arcing-down quality, the visual register of peregrine-falcon-and-stooping-hawk-swoop hand-fast-descending-and-arcing-down peregrine-falcon-and-stooping-hawk-and-eagle swooped-and-fast-descending-and-arcing-down surfaces under peregrine-falcon-and-stooping-hawk-and-eagle cliff-face-and-moorland-and-open-sky raptor-stoop-light. Sits at the modifier-and-mood end of the grid, parallel to flit and glide in usage.

Forest
noun

The dense canopy of a temperate or tropical woodland — oak, beech, pine, eucalyptus, mahogany — wherever leaves close above to filter the light below. Forest green refers to the average reflectance of a healthy mid-summer canopy seen from below: a saturated, slightly muted green with the matte finish of layered chlorophyll. Deeper than fern, cooler than olive, with the ecological weight of a word that has named every wooded biome on Earth.

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.
