Plumbed Wine

#48003b
Notes

Plumbed Wine (#48003B) 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 (311°, 100%, 14%) 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

Plumbed
adjective

Latin plumbum, lead — past-participle of plumb (to measure depth with a lead-weighted line). As a color modifier, plumbed implies a deep-and-cool quality measured-to-its-fullest-depth, the dark cool-gray of lead-and-pewter metallic surfaces. Sits at the deep-and-cool end of the grid, parallel to fathomless with metallic register.

Wine
noun

Fermented grape juice — the universal red of viticulture from Tuscany to Mendoza. Wine as a color refers specifically to a young Cabernet Sauvignon or Syrah in a glass: a saturated, slightly red-shifted deep purple-red with the optical clarity of a fluid free of suspended solids. Cooler than burgundy, warmer than mulberry, with the agricultural weight of a fluid whose color comes principally from anthocyanin pigment in the grape skin.

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.
