Bright Vermont

#afbb20
Notes

Bright Vermont (#AFBB20) 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 (65°, 71%, 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

Bright
adjective

Old English beorht, shining, luminous — cognate with the German Bracht, splendor. Applied to color since at least the medieval period for hues that read as luminous: not just light in value but optically active, as if scattering more light back than a dimmer color of the same lightness would. Sits at the bright-bucket center alongside vivid and brilliant.

Vermont
noun

The American Northeast state — and the warm gold-yellow of Vermont sugar-maple foliage at peak fall color and Vermont Grade-A medium-amber maple syrup. Vermont refers to a Vermont Acer saccharum canopy in mid-October: a saturated, slightly red yellow-orange with the optical complexity of carotenoid-rich autumn leaves.

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.
