Loud Floret

#acbb21
Notes

Loud Floret (#ACBB21) 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 (66°, 70%, 43%) 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 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.

Floret
noun

A small individual flower in a clustered inflorescence — particularly the small yellow florets of composite-family flowers (sunflower, daisy, calendula). The color refers to a single sunflower floret: a saturated, slightly red yellow with the matte finish of small disc-floret. Brighter than corn.

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.
