Noble Carthage

#812991
Notes

Noble Carthage (#812991) is a true violet with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (291°, 56%, 36%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Noble
adjective

Latin nōbilis, well-known / illustrious — sharing root with gnōscere (to know). As a color modifier, noble implies a saturated-and-dignified-and-aristocratic quality, the deep-rich color of pre-modern European noble-class hereditary-aristocratic livery-and-armorial bearings. Sits at the bold-and-aristocratic end of the grid, parallel to aristocratic and highborn in usage.

Carthage
noun

Phoenician colonial capital on the Tunis coast (founded 814 BCE) — and a major secondary Tyrian purple production site supplying the western Mediterranean trade network. Carthage color refers to a Carthaginian trade-textile fragment from the Byrsa hill citadel: a saturated, slightly cool deep violet with the matte finish of multi-bath Bolinus brandaris shellfish dye on hand-loomed Punic wool.
