Untroubled Smithsonite

#b1fde3
Notes

Untroubled Smithsonite (#B1FDE3) is a soft teal with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (159°, 95%, 84%) places it in the highly saturated band at a light lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Untroubled
adjective

Latin turbāre, to disturb — negative-prefix un- plus past-participle of trouble. As a color modifier, untroubled implies a clear-and-calm-and-undisturbed quality where the hue carries no visual agitation. Sits at the crisp-and-calm end of the grid, parallel to serene and placid in usage.

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.
