Lustrous Celadon

#20d2b1
Notes

Lustrous Celadon (#20D2B1) 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°, 74%, 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.

Celadon
noun

The pale-green iron-ash glaze fired on Chinese and Korean stoneware since the Han dynasty — Goryeo celadon and Longquan ware reaching their peak between the tenth and thirteenth centuries. The color refers to a glazed Goryeo bowl in display lighting: a soft, slightly muted green-blue with the high shine of vitrified silica. Cooler than jade, warmer than seafoam, with the museum weight of a ceramic tradition prized in East Asian imperial courts.
