Prismatic Celadon

#28e9a3
Notes

Prismatic Celadon (#28E9A3) 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 (158°, 81%, 54%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Prismatic
adjective

Greek prísma, prism — adjectival suffix -ic. As a color modifier, prismatic implies a saturated-and-multi-spectrum-decomposed quality, the bright color of crystal-prism and cut-glass-chandelier light-refraction-spectrum decomposition. Sits at the bright-and-shifting end of the grid, parallel to iridescent and spectral in usage.

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.

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.
