Composed Bordeaux

#b52d1a
Notes

Composed Bordeaux (#B52D1A) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (7°, 75%, 41%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Composed
adjective

The past participle of compose, to arrange together — used as a color modifier for hues that read as deliberate and balanced. Composed black, composed gray: the saturation is moderate, the hue is calmly positioned without aggression. Sits at the bold-and-quiet edge of the grid near settled and resolute.

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.
