Noble Magenta

#870369
Notes

Noble Magenta (#870369) is a deep magenta 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 (314°, 96%, 27%) 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.

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.

Magenta
noun

A synthetic aniline dye (fuchsine) introduced in 1859 and renamed in 1860 to commemorate the Franco-Sardinian victory over Austria at the Battle of Magenta in northern Italy. The dye produced the first vivid pink-purple textile color cheaply available to mass markets. The color refers to a freshly magenta-dyed silk: a saturated, slightly cool deep pink-purple with the satiny finish of synthetic-dyed natural fiber. Cooler than fuchsia, warmer than violet.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
