Hygienic Tirkizhna

#57d5bd
Notes

Hygienic Tirkizhna (#57D5BD) is a true teal with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (169°, 60%, 59%) places it in the balanced 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

Hygienic
adjective

Greek hygieinós, healthful — derived from Hygieia (goddess of health). As a color modifier, hygienic implies a clear-and-medical-clean quality, the crisp color of Mid-Century-Modern clinical-and-hospital interior-architecture surfaces. Sits at the crisp-and-clean end of the grid, parallel to sanitary and sterile 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.
