Quakerly Nero

#1d031c
Notes

Quakerly Nero (#1D031C) is a deep violet 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 (302°, 81%, 6%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Nero color refers to a Venetian capa nera of nero d'avorio (ivory-black) pigment: a saturated, slightly cool deep black with the matte finish of multi-bath bone-and-iron-tannin dye on woven bombycin silk. The Italian color tradition distinguishes nero pece (pitch-black) from nero corvino (raven-black).
