Crypted Brazilwood

#64130b
Notes

Crypted Brazilwood (#64130B) 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 (5°, 80%, 22%) 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

Crypted
adjective

Greek kryptē, hidden chamber — past-participle of crypt. As a color modifier, crypted implies the deep-and-funereal-and-architectural quality of medieval European cathedral-and-basilica royal-crypt-chamber underground architecture, particularly the Saint-Denis and Westminster-Abbey royal-funerary tradition. Sits at the deep-and-funereal end of the grid, parallel to sepulchral and tomblike.

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.
