Bold Luna Forest

#318f30
Notes

Bold Luna Forest (#318F30) 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 (119°, 50%, 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

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.

Luna
modifier

Latin luna, moon. As a color modifier, luna implies a moonlit-and-silver-and-pale-night quality, the visual register of full-moon-and-Selene-Diana-Luna hand-moonlit-and-silver-and-pale-night full-moon-and-Selene-Diana-Luna-and-Mare-Tranquillitatis luna-and-moonlit-and-silver-and-pale-night surfaces under full-moon-and-Selene-Diana-Luna-and-Mare-Tranquillitatis night-meadow-and-tarn-and-monastic-cloister silver-night-light. Sits at the modifier-and-cosmic end of the grid, parallel to sol and terra 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.
