Vitreous Bourbon

#ad9020
Notes

Vitreous Bourbon (#AD9020) is a true amber with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (48°, 69%, 40%) 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

Vitreous
adjective

Latin vitreus, glass-like — derived from vitrum (glass). As a color modifier, vitreous implies a clear-and-glassy quality where the hue carries the optical clarity of polished crown-glass. Sits at the crisp-and-clear end of the grid, parallel to pellucid and crystalline in usage.

Bourbon
noun

American corn-based whiskey — distilled and aged in new charred-oak barrels under U.S. federal regulation. The charring gives bourbon its characteristically saturated warm brown color. The color refers to a 10-year-old Kentucky straight bourbon: a saturated, slightly red-shifted warm brown with the optical depth of new-oak-aged spirit.

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.
