Hefty Blank Forest

#105b08
Notes

Hefty Blank Forest (#105B08) 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 (114°, 84%, 19%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Hefty
adjective

Old English hefig, heavy — adjectival suffix -y. As a color modifier, hefty implies a saturated-and-substantial-and-weighty quality where the hue carries the visual heft of a hand-cast pig-iron object. Sits at the bold-and-weighty end of the grid, parallel to substantial and weighty in usage.

Blank
modifier

Old French blanc, white-or-empty. As a color modifier, blank implies an unmarked-and-empty-and-pristine quality, the visual register of fresh-page-and-primed-canvas-blank hand-unmarked-and-empty-and-pristine fresh-page-and-primed-canvas-and-white-room blanked-and-unmarked-and-empty-and-pristine surfaces under fresh-page-and-primed-canvas-and-white-room studio-and-stationer-and-gallery untouched-light. Sits at the modifier-and-mood end of the grid, parallel to void and hollow 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.
