Stormy Stichtite

#3b116a
Notes

Stormy Stichtite (#3B116A) is a deep indigo with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (268°, 72%, 24%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Stormy
adjective

Old English storm, storm — adjectival suffix -y. As a color modifier, stormy implies a deep-and-turbulent-and-cool-shifted quality, the dark cool-gray of Force-9-gale atmospheric-turbulence sky. Sits at the deep-and-turbulent end of the grid, parallel to thunderous and tempestuous in atmospheric register.

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.
