Bold Naples

#b63404
Notes

Bold Naples (#B63404) is a true orange 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 (16°, 96%, 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 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.

Naples
noun

Naples yellow (lead-tin yellow) — a lead-tin oxide pigment used in European oil painting from the medieval period through the nineteenth century. The color refers to Naples-yellow pigment in a Vermeer painting: a saturated, slightly red yellow-orange with the matte finish of lead-and-tin-based pigment. Cooler than turmeric.
