Untroubled Stichtite

#63467a
Notes

Untroubled Stichtite (#63467A) is a true indigo 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 (273°, 27%, 38%) 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 lime. 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.

Stichtite
noun

Rare violet-pink chromium-bearing mineral first described from the Dundas deposits of Tasmania in 1910 by Robert Sticht. Stichtite color refers to a polished Dundas stichtite-and-serpentine cabochon: a saturated, slightly cool deep violet with the silky finish of fibrous magnesium-chromium hydroxide-carbonate. The mineral is the chromium-substituted analog of brugnatellite, valued in lapidary work for its banded color.

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.
