Certain Sangria

#b31056
Notes

Certain Sangria (#B31056) is a true 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 (334°, 84%, 38%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Certain
adjective

Latin certus, fixed / sure — sharing root with English concern and certify. As a color modifier, certain implies a saturated-and-unambiguous quality where the hue declares its character without hesitation. Sits at the bold-and-confident end of the grid, parallel to assured and decisive in usage.

Sangria
noun

Spanish for bleeding — the wine punch named for its color, not the other way around. The color is the deep red of Tempranillo or Garnacha aerated with citrus and fruit: a warm, slightly translucent red-violet that catches light through a glass jug. Less black than burgundy, warmer than wine, with the dusty rim of a long afternoon.
