Lustrous Sardinia

#28caa6
Notes

Lustrous Sardinia (#28CAA6) 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 (167°, 67%, 47%) 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

Lustrous
adjective

From the Latin lustrare, to illuminate — used as a color word since the seventeenth century for hues with the slight specular shine of polished metal or silk. Lustrous green, lustrous gold: the implication is moderate-to-high saturation combined with surface reflectivity. Sits at the bright-and-glossy corner alongside gleaming.

Sardinia
noun

The Italian Mediterranean island — and the saturated turquoise of Sardinian Costa Smeralda (Emerald Coast) at Cala di Volpe and Spiaggia del Principe. Sardinia refers to a Costa Smeralda lagoon: a saturated, slightly cool deep blue-green with the optical clarity of cold Mediterranean water.

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.
