Sure Vermont

#a39c63
Notes

Sure Vermont (#A39C63) is a true amber 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 (53°, 26%, 51%) places it in the muted 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

Sure
adjective

Old French seur, certain — used as a color modifier since the medieval period for hues that read as confident and stable. Sure red, sure blue: moderate saturation combined with optical commitment. Sits at the crisp-bucket center alongside steady and true.

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.
