Vibrant Floret

#aca11d
Notes

Vibrant Floret (#ACA11D) is a true yellow with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (55°, 71%, 39%) 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

Vibrant
adjective

From the Latin vibrare, to shake — used as a color word since the seventeenth century for hues that read as alive and resonant. Vibrant orange, vibrant green: the implication is saturation combined with the optical impression of slight motion or energy. Sits at the bright-bucket center alongside vivid and lively.

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.
