Resolute Jolly Forest

#339833
Notes

Resolute Jolly Forest (#339833) 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 (120°, 50%, 40%) 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

Resolute
adjective

From the Latin resolutus, unwavering — used as a color modifier in literary contexts for hues that read as committed and unmoving. Resolute blue, resolute green: the saturation is full, the hue holds its position without shifting under different light. Sits in the bold-bucket center alongside strong and true, with slightly more focus on stability than presence.

Jolly
modifier

Old French jolif, festive-and-pretty. As a color modifier, jolly implies a hearty-and-warm-and-festive quality, the visual register of Dickens-Christmas-and-Falstaffian-jolly hand-hearty-and-warm-and-festive Dickens-Christmas-and-Falstaffian-and-Pickwickian jollied-and-hearty-and-warm-and-festive surfaces under Dickens-Christmas-and-Falstaffian-and-Pickwickian goose-and-plum-pudding-and-roaring-hearth Christmas-Eve-light. Sits at the modifier-and-mood end of the grid, parallel to merry and mirth 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.
