Loud Pommery

#acc903
Notes

Loud Pommery (#ACC903) 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 (69°, 97%, 40%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Loud
adjective

Old English hlūd, making noise — borrowed metaphorically as a color word since the nineteenth century. Loud red, loud yellow: a color so saturated it announces itself without needing surrounding context. Sits in the bright-bucket extreme alongside electric and striking. Carries a slightly pejorative implication of excess.

Pommery
noun

The Champagne house founded in Reims in 1858 — and the saturated yellow of Pommery Brut Royal vintage labeling. Pommery refers to a vintage Pommery Champagne in a flute: a soft, slightly cool warm pale yellow with the optical clarity of long-aged sparkling wine. Warmer than champagne.

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.
