Dominant Bordeaux

#870c39
Notes

Dominant Bordeaux (#870C39) is a deep magenta with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (338°, 84%, 29%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Dominant
adjective

Latin dominārī, to rule — present-participle of dominate. As a color modifier, dominant implies a saturated-and-leading quality where the hue claims visual precedence over neighboring colors in the surrounding palette. Sits at the bold-and-imperative end of the grid, parallel to commanding and authoritative.

Bordeaux
noun

The French wine region — and the deep red of Cabernet Sauvignon-and-Merlot blends from the Médoc and Saint-Émilion. Bordeaux as a color refers specifically to a young Médoc in a glass: a deep, slightly red-purple-shifted dark red with the optical clarity of high-tannin wine. Deeper than burgundy, cooler than wine.

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.
