Straightforward Atacamite

#3b894e
Notes

Straightforward Atacamite (#3B894E) is a true 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 (135°, 40%, 38%) places it in the balanced 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

Straightforward
adjective

English compound straight + forward — sharing root with German geradeaus. As a color modifier, straightforward implies a clear-and-direct-and-unencumbered quality where the hue carries the visual register of clear-aim-and-uncomplicated character. Sits at the crisp-and-honest end of the grid, parallel to candid and direct in usage.

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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
