Lordly Sleek Forest

#0f5a03
Notes

Lordly Sleek Forest (#0F5A03) 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 (112°, 94%, 18%) 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

Lordly
adjective

Old English hlāford-līc, lord-like — adjectival suffix -ly. As a color modifier, lordly implies a saturated-and-aristocratic-and-haughty quality, the deep-rich color of pre-modern English-and-French manorial-aristocracy livery and hereditary-estate household-textile. Sits at the bold-and-aristocratic end of the grid, parallel to princely and patrician.

Sleek
modifier

Middle Dutch sleeck, smooth. As a color modifier, sleek implies a smooth-and-streamlined quality, the visual register of Mid-Century-Modern-and-Streamline-Moderne-sleek hand-streamlined-and-aerodynamic-and-polished aluminum-and-chrome-and-bakelite Mid-Century-Modern-and-Streamline-Moderne sleek-and-streamlined surfaces under Mid-Century-Modern-and-Streamline-Moderne sleek-and-polished light. Sits at the modifier-and-texture end of the grid, parallel to gloss and shine 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.
