Plumbed Damson

#50337e
Notes

Plumbed Damson (#50337E) is a true indigo with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (263°, 42%, 35%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary lime. 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.

Damson
noun

Prunus domestica subsp. insititia, the small dark plum of European orchards — too tart to eat fresh but unmatched for jam, gin-flavoring, and English plum pudding. Named for Damascus, the city through which it spread westward in antiquity. The color refers to a ripe damson on the tree: a deep, slightly red-shifted purple-black with the heavy bloom of waxy fruit surface. Deeper than plum, cooler than wine.

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.
