Plumbed Lilac

#660f5d
Notes

Plumbed Lilac (#660F5D) is a deep violet 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 (306°, 74%, 23%) 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

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.

Lilac
noun

Syringa vulgaris, the Balkan-native shrub whose pale purple panicles perfume European gardens in May. The Persian nilak, bluish, became the Arabic līlak and then the Spanish lila before reaching English in the seventeenth century. The color refers to a fresh lilac flower cluster: a soft, slightly muted pale purple with the matte finish of densely packed four-petaled florets. Lighter than mauve, cooler than orchid.
