Clear Atacamite

#558f7a
Notes

Clear Atacamite (#558F7A) is a true teal 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 (158°, 25%, 45%) places it in the muted band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Clear
adjective

From the Latin clarus, bright, distinct — used as a color modifier since the medieval period for hues without haze or mixing. Clear blue sky, clear green water: the implication is moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clean and true.

Atacamite
noun

A copper-chloride mineral named for the Atacama Desert of Chile where it was first described. Atacamite forms in arid copper-mineral deposits worldwide. The color refers to a clean atacamite crystal: a saturated, slightly cool deep emerald-green with the satin finish of crystallized secondary copper mineral.
