Plentiful Tirkizhna

#278f40
Notes

Plentiful Tirkizhna (#278F40) is a true green 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 (134°, 57%, 36%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Plentiful
adjective

Old French plentif, abundant — adjectival suffix -ful, derived from Latin plēnitās (fullness). As a color modifier, plentiful implies a saturated-and-generous quality where the hue carries rich visual abundance without restraint. Sits at the bold-and-saturated end of the grid, parallel to abundant and bountiful.

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.

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.
