Bastioned Carmine

#b81a8c
Notes

Bastioned Carmine (#B81A8C) is a true magenta with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (317°, 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bastioned
adjective

Italian bastionato, fortified-with-bastions — past-participle of bastion, derived from bastia (fortified-tower). As a color modifier, bastioned implies a saturated-and-fortified-and-projecting quality, the deep-rich color of Vauban-period military-fortress star-fort projecting-bastion stone-architecture. Sits at the bold-and-fortified end of the grid, parallel to fortified and buttressed.

Carmine
noun

The deep red-purple dye extracted from cochineal scale insects (Dactylopius coccus) — harvested in pre-Columbian Mexico and shipped to Europe by the Spanish empire as an export second only to silver. The color refers to fresh carmine pigment in solution: a saturated, slightly cool deep red-purple with the brilliance of a dye thirty times stronger than kermes. Cooler than crimson, warmer than wine, with the colonial-trade weight of a pigment that funded an empire.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
