Twilit Brazilwood

#831310
Notes

Twilit Brazilwood (#831310) is a deep 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 (2°, 78%, 29%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Twilit
adjective

An adjectival form of twilight, coined in the late nineteenth century. Twilit describes a color seen at twilight — the slight cooling and desaturation that low ambient light introduces. Sits in the deep-and-cool corner, lighter than somber and bluer than shadowed. Almost exclusively literary.

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.

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.
