Commanding Groen

#318a09
Notes

Commanding Groen (#318A09) 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 (101°, 88%, 29%) 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

Commanding
adjective

Latin commendāre, to entrust / order — present-participle of command. As a color modifier, commanding implies a saturated-and-authoritative quality where the hue claims visual leadership of its surrounding palette. Sits at the bold-and-authoritative end of the grid, parallel to authoritative and imperial in usage.

Groen
noun

The Dutch word for green — used for the Hollands Groen of Delft Blue's complementary glaze and the green polders of Dutch reclaimed-land farmland. The color refers to a Delft-pottery green underglaze: a saturated, slightly cool green with the matte finish of fired tin-glaze. The Dutch cousin of green.
