Fortified Brazilwood

#b30725
Notes

Fortified Brazilwood (#B30725) is a true red 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 (350°, 92%, 36%) 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

Fortified
adjective

Latin fortificāre, to make strong — past-participle of fortify. As a color modifier, fortified implies a saturated-and-strengthened-and-defensive quality, the deep-rich color of Vauban-style military-fortification stone-and-earth rampart-and-bastion architecture. Sits at the bold-and-fortified end of the grid, parallel to bastioned and armored.

Brazilwood
noun

Caesalpinia echinata, the dye-source tree of Atlantic-coast South America — so abundant in Portuguese-controlled territory that it gave the country its name. The color refers to brazilein-dyed silk: a saturated, slightly cool deep red with the warm-tone of brazilwood pigment. Deeper than madder, warmer than cochineal.
