Bold Sappanwood

#b24451
Notes

Bold Sappanwood (#B24451) is a true red with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (353°, 45%, 48%) 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 teal. 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.

Sappanwood
noun

Caesalpinia sappan, the Asian counterpart to brazilwood — used as a red dye source in Indian, Indonesian, and Japanese textile tradition. The color refers to sappanwood-dyed cotton: a saturated, slightly cool deep red with the warm tone of brazilein pigment. The Asian cousin of brazilwood.
