Sinister Bordeaux
Sinister Bordeaux (#840835) 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°, 89%, 27%) 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
Latin sinister, left / unlucky — used in classical-augury for the unfavorable left-hand-side of bird-flight omen-reading. As a color modifier, sinister implies a deep-and-foreboding-and-uncanny quality, the dark of Gothic-novel atmospheric-shadow and threatening-presence. Sits at the deep-and-uncanny end of the grid, parallel to foreboding and menacing in atmospheric register.
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.
