Resounding Pier Forest

#258b28
Notes

Resounding Pier Forest (#258B28) is a true green with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (122°, 58%, 35%) 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

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.

Pier
modifier

Old French piere, stone / pier. As a color modifier, pier implies a sea-extending-walkway quality, the visual register of Brighton-and-Blackpool Victorian-period iron-and-wooden sea-pier pleasure-and-amusement promenade surfaces under bright English-seaside Victorian-pier light. Sits at the modifier-and-place end of the grid, parallel to jetty and wharf 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.
