Plumbed Spruce

#223921
Notes

Plumbed Spruce (#223921) is a deep green 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 (118°, 27%, 18%) places it in the muted 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 violet. 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.

Spruce
noun

The genus Picea, the spruces of the boreal and montane forests — Sitka, Norway, blue, white, black — the conifer that frames timberline across the northern hemisphere. The color refers to fresh spruce needles: a deep, slightly blue-shifted green with the matte finish of resin-coated foliage. Cooler than fern, warmer than teal, with the resinous cold-air association of a high-altitude or high-latitude evergreen.
