Vibrant Yolk

#aeb628
Notes

Vibrant Yolk (#AEB628) 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 (63°, 64%, 44%) 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.

Yolk
noun

The yellow center of a chicken egg — colored by carotenoid pigments in the hen's feed, ranging from pale lemon (commercial barn-raised) to deep orange (pasture-raised, marigold-supplemented). The color refers to a fresh free-range yolk against the white: a saturated, slightly orange-shifted yellow with the satiny surface of a vitellus membrane. Warmer than canary, deeper than sunflower; the unifying yellow of breakfast.

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.
