Imposing Hunter

#153f05
Notes

Imposing Hunter (#153F05) 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 (103°, 85%, 13%) 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

Imposing
adjective

Latin impōnere, to place upon — present-participle of impose. As a color modifier, imposing implies a deep-and-massive-and-architectural quality, the dark cool-gray of Citadel-and-Cathedral monumental architecture against the sky. Sits at the deep-and-architectural end of the grid, parallel to towering and looming in scale.

Hunter
noun

A deep, slightly muted green named for the wool jackets worn by British and American sportsmen for shooting and hunting since the late nineteenth century — chosen for camouflage in temperate woodland. The color refers to the dye on a traditional hunter-green Barbour or tweed: a deep, slightly blue-shifted green with the matte finish of a heavyweight wool. Darker than forest, cooler than holly.

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.
