Armored Ruff Forest

#037d18
Notes

Armored Ruff Forest (#037D18) 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 (130°, 95%, 25%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Armored
adjective

Old French armëure, armor — past-participle of armor, derived from Latin arma (weapons). As a color modifier, armored implies a saturated-and-armor-clad-and-defensive quality, the deep-rich color of medieval-knight full-plate-armor visible-and-formidable battle-presence. Sits at the bold-and-fortified end of the grid, parallel to ironclad and shielded.

Ruff
modifier

Old English ruffe, Elizabethan-pleated-collar. As a color modifier, ruff implies a starched-and-Elizabethan-pleated-collar quality, the visual register of Elizabethan-and-Spanish-Habsburg-ruff hand-starched-and-Elizabethan-pleated-collar Elizabethan-and-Spanish-Habsburg-ruff-and-Holbein-portrait ruff-and-starched-and-Elizabethan-pleated-collar surfaces under Elizabethan-and-Spanish-Habsburg-ruff-and-Holbein-portrait Tudor-and-Spanish-Habsburg-court starched-collar-light. Sits at the modifier-and-textile end of the grid, parallel to gown and frock 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.
