Noble Pelt Ruby

#811b55
Notes

Noble Pelt Ruby (#811B55) 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 (326°, 65%, 31%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary teal. 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.

Pelt
modifier

Old French pellete, small-skin. As a color modifier, pelt implies a fur-with-skin-and-hide quality, the visual register of fur-trapper-and-Hudson-Bay-Pelt hand-trapped-and-skinned beaver-and-otter-and-mink hand-trapped-fur-pelt-and-hide surfaces under Hudson-Bay-and-fur-trapper hand-trapped pelt-and-hide trading-post light. Sits at the modifier-and-texture end of the grid, parallel to hide and fur in usage.

Ruby
noun

From the Latin ruber — simply, red. The gemstone is a chromium-tinged corundum, harder than anything in nature except diamond, and so saturated that a fine Burmese pigeon's blood ruby at auction outpaces a comparable diamond by weight. The color borrows the gem's confidence: a clear, glassy red without the brown of garnet or the blue of crimson.

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.
