Hushed Charcoal

#091800
Notes

Hushed Charcoal (#091800) is a deep lime 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 (98°, 100%, 5%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Hushed
adjective

The past participle of hush, to silence — used as a color modifier since the late nineteenth century for hues that read as if turned down. Hushed pink, hushed lavender: low saturation combined with optical quietness. Sits at the hushed-bucket center alongside muted.

Charcoal
noun

The black porous solid produced by heating wood in low-oxygen conditions — driving off volatiles and leaving high-carbon residue. Used since prehistory for cave drawing, smelting, and (more recently) art-school sketching. The color refers to a fresh willow charcoal stick on white paper: a soft, slightly muted gray-black with the matte finish of dry porous carbon. Warmer than graphite, drier than coal, with the studio-and-forge association of a material older than iron.
