Starched Smaragdite

#216b2b
Notes

Starched Smaragdite (#216B2B) is a deep green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (128°, 53%, 27%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Starched
adjective

Old English stercan, to stiffen — past-participle of starch. As a color modifier, starched implies a clear-and-stiff-and-formal quality, the crisp color of Edwardian-period formal-evening-shirt-and-collar starched-and-pressed dress-attire. Sits at the crisp-and-finished end of the grid, parallel to pressed and ironed in usage.

Smaragdite
noun

An emerald-green variety of amphibole — closely related to actinolite, found in metamorphic rocks of the Italian Alps. The color refers to a polished Italian smaragdite: a saturated, slightly muted deep green with the slight fibrous texture of amphibole crystallography.
