Muted Smithsonite

#638b7e
Notes

Muted Smithsonite (#638B7E) 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 (161°, 17%, 47%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Muted
adjective

The past participle of mute, to silence — used as a color modifier since the seventeenth century for hues that have been reduced from full saturation. Muted green, muted blue: low-to-moderate saturation combined with optical restraint. Sits at the hushed-bucket center alongside hushed and dusky.

Smithsonite
noun

A zinc carbonate mineral — named for English chemist James Smithson (founder of the Smithsonian Institution). The blue-green variety is mined principally in New Mexico's Magdalena Mountains. The color refers to a polished blue-green smithsonite cabochon: a soft, slightly cool deep blue-green with the satin finish of botryoidal zinc-carbonate mineral.
