Even Tirkizhna

#28aca2
Notes

Even Tirkizhna (#28ACA2) is a true cyan 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 (175°, 62%, 42%) 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

Even
adjective

Old English efen, flat, equal — used as a color modifier since the medieval period for hues that read as uniformly distributed across a surface. Even gray, even tan: the implication is moderate saturation combined with optical uniformity. Sits at the crisp-bucket center alongside steady and balanced.

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.
