Rich Echeveria

#218937
Notes

Rich Echeveria (#218937) 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 (133°, 61%, 33%) 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

Rich
adjective

Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.

Echeveria
noun

The genus Echeveria — Mexican rosette-forming succulents named for the eighteenth-century botanical illustrator Atanasio Echeverría y Godoy. Cultivated globally as ornamental plants for their geometric blue-green form. The color refers to a fresh Echeveria elegans rosette: a soft, slightly cool silver-green-blue with the matte velvet finish of waxy succulent leaves.
