Glowy Yùhuáng

#ceea40
Notes

Glowy Yùhuáng (#CEEA40) is a true yellow with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (70°, 80%, 58%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Glowy
adjective

Old English glōwan, to glow — adjectival suffix -y. As a color modifier, glowy implies a saturated-and-soft-emitting-and-warm quality, the bright color of fireside-and-candle-lit interior atmospheric-warmth surface emission. Sits at the bright-and-warm end of the grid, parallel to glowing and luminous in usage.

Yùhuáng
noun

Literally jade-yellow in Chinese — a soft, slightly cool pale yellow used in ceremonial hetian nephrite jade and in the silks of Qing-dynasty consort robes. The color refers to a polished pale-yellow nephrite cabochon: a soft, slightly cool pale yellow with the satin finish of fine jade.

Wide gamut

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
