Plumbed Mûre
Plumbed Mûre (#531C6B) is a deep 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 (282°, 59%, 26%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
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.
French for blackberry / mulberry (Rubus fruticosus / Morus nigra) — the deep-violet aggregate-drupe of European hedgerows and Morus tree-fruit, both important anthocyanin-rich autumn fruits. Mûre color refers to a freshly picked Rubus fruticosus aggregate-drupe in a Berry hedgerow: a saturated, slightly cool deep violet with the matte finish of anthocyanin-rich aggregate-drupelet cluster on hand-collected fruit.
