Bold Pourpre

#b8372b
Notes

Bold Pourpre (#B8372B) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (5°, 62%, 45%) 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

Bold
adjective

Old English beald, brave, courageous — a quality word that crossed over to color in the late seventeenth century. Bold describes a color that asserts itself: high saturation combined with mid lightness, where the hue presents itself without compromise. Sits at the center of the bold-bucket grid, near strong and rich. Closer to a presence word than a pigment word.

Pourpre
noun

French for purple in its classical sense — the deep red-purple of Tyrian dye and the pourpre cardinalice of medieval French ecclesiastical dress. The color refers to a pourpre-dyed French silk: a saturated, slightly cool deep red-purple with the satin finish of plant-and-shell dye. The French cousin of porpora.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
