Plumbed Echinacea

#37162c
Notes

Plumbed Echinacea (#37162C) is a deep magenta 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 (320°, 43%, 15%) 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.

Echinacea
noun

North American purple coneflower (Echinacea purpurea) — a midwestern-prairie Asteraceae perennial with deep-magenta drooping ray-flowers and a prominent rust-orange disk-cone center. Echinacea color refers to a fully opened Echinacea purpurea ray-flower in late-summer light: a saturated, slightly cool deep magenta with the velvet finish of fresh drooping ray-flowers. The Greek genus name echínos (hedgehog) refers to the prickly disk.
