Noble Glade

#17781e
Notes

Noble Glade (#17781E) 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 (124°, 68%, 28%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Noble
adjective

Latin nōbilis, well-known / illustrious — sharing root with gnōscere (to know). As a color modifier, noble implies a saturated-and-dignified-and-aristocratic quality, the deep-rich color of pre-modern European noble-class hereditary-aristocratic livery-and-armorial bearings. Sits at the bold-and-aristocratic end of the grid, parallel to aristocratic and highborn in usage.

Glade
noun

An open clearing in a forest — often grassy, where sunlight reaches the ground unobstructed. The Old English glæd (bright) names the brightness of the clearing relative to its surrounding shade. Glade color refers to a sunlit forest clearing in summer: a saturated, slightly yellow-green with the matte finish of sun-bright grass-and-fern. Lighter than bosco.
