Domestic Nero

#150301
Notes

Domestic Nero (#150301) 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 (6°, 91%, 4%) 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

Domestic
adjective

Latin domesticus, of-the-house — derived from domus (house). As a color modifier, domestic implies a neutral-and-household-and-everyday quality, the neutral color of Vermeer-and-Dutch-Genre-painting household-and-everyday interior-and-textile-and-table-still-life finish, often featuring whitewashed walls and earthen-tiled floors. Sits at the neutral-and-traditional end of the grid, parallel to homey and cottage in usage.

Nero
noun

Italian for black — derived from Latin niger via Tuscan dialect. 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).
