Utilitarian Tirkizhna

#137357
Notes

Utilitarian Tirkizhna (#137357) is a deep teal 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 (163°, 72%, 26%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Utilitarian
adjective

Latin ūtilitās, usefulness — adjectival suffix -ian. As a color modifier, utilitarian implies a clear-and-purpose-fit-and-stripped-down quality, the crisp color of Shaker-and-Quaker anti-ornamental functional-and-no-frills craft tradition. Sits at the crisp-and-functional end of the grid, parallel to functional and workmanlike in usage.

Tirkizhna
noun

The Slavic word for turquoise-colored — used across Russian, Ukrainian, and Polish color vocabulary for the saturated blue-green of Iranian and Central Asian turquoise. The color refers to a tirkizhna-glazed samovar: a saturated, slightly cool deep blue-green with the high gloss of fired ceramic.
