Plumbed Liatris

#2f3683
Notes

Plumbed Liatris (#2F3683) is a true blue 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 (235°, 47%, 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 yellow. 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.

Liatris
noun

North American prairie blazing star (Liatris spicata) — its dense vertical spike of disk-flowers blooms top-down in late summer across midwestern tallgrass prairie. Liatris color refers to a fully bloomed Liatris spicata spike on a Wisconsin prairie remnant: a saturated, slightly cool deep blue-violet with the velvet finish of fresh disk-flowers. Slightly warmer than Verbena and cooler than Lythrum salicaria.

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.
