Straightforward Tirkizhna

#25c1a5
Notes

Straightforward Tirkizhna (#25C1A5) is a true teal with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (169°, 68%, 45%) 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

Straightforward
adjective

English compound straight + forward — sharing root with German geradeaus. As a color modifier, straightforward implies a clear-and-direct-and-unencumbered quality where the hue carries the visual register of clear-aim-and-uncomplicated character. Sits at the crisp-and-honest end of the grid, parallel to candid and direct 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.
