Open Beaujolais

#ac6378
Notes

Open Beaujolais (#AC6378) is a true red 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 (343°, 31%, 53%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Open
adjective

Old English open, unobstructed — used as a color modifier since the eighteenth century for hues that read as airy or uncrowded. Open blue, open green: moderate saturation combined with optical spaciousness, the slight visual breath of a hue that doesn't crowd the surface it covers. Sits at the crisp-bucket center alongside clear.

Beaujolais
noun

The French wine region just south of Burgundy — and the Gamay-based reds of Beaujolais Nouveau. The color refers to a fresh Beaujolais Nouveau in a glass: a saturated, slightly cool red with the optical brightness of low-tannin young wine. Lighter than Burgundy, brighter than Chianti.

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.
