Smoldering Chrysocolla

#148a32
Notes

Smoldering Chrysocolla (#148A32) 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 (135°, 75%, 31%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Smoldering
adjective

The progressive participle of smolder, to burn slowly without flame. Used as a color word since the late nineteenth century for the deep reds and oranges of barely-flame coal — the warm saturated darks where the heat is internal rather than emitted. Sits in the bold-and-warm corner, slightly less luminous than burning and slightly less calm than rich.

Chrysocolla
noun

A copper-aluminum hydrous silicate — saturated blue-green, mined principally in copper-mineral deposits of Arizona, Israel, and the Democratic Republic of the Congo. The color refers to a polished chrysocolla cabochon: a saturated, slightly cool deep blue-green with the matte finish of secondary copper mineral. Cooler than malachite.
