Resounding Sloop Forest

#136c1f
Notes

Resounding Sloop Forest (#136C1F) 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 (128°, 70%, 25%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Resounding
adjective

Latin resonāre, to echo back — present-participle of resound. As a color modifier, resounding implies a saturated-and-echoing-and-imposing quality where the hue reverberates visually like a cathedral-bell ring. Sits at the bold-and-resonant end of the grid, parallel to resonant and booming in usage.

Sloop
modifier

Dutch sloep, single-masted-vessel. As a color modifier, sloop implies a single-masted-fore-and-aft-rigged-vessel quality, the visual register of American-and-Dutch-sloop hand-built single-masted-fore-and-aft-rigged sloop-and-cutter maritime-architecture surfaces under American-and-Dutch sloop-and-cutter maritime sailing light. Sits at the modifier-and-nautical end of the grid, parallel to skiff and hull 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.
