Reinforced Bordeaux

#b73315
Notes

Reinforced Bordeaux (#B73315) 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 (11°, 79%, 40%) places it in the highly saturated band at a mid 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Reinforced
adjective

Latin re- plus inforce — past-participle of reinforce. As a color modifier, reinforced implies a saturated-and-doubled-up-and-strengthened quality where the hue carries layered pigmentation for maximum visual presence. Sits at the bold-and-fortified end of the grid, parallel to fortified and buttressed.

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.
