Sooty Pasqueflower

#372f96
Notes

Sooty Pasqueflower (#372F96) 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 (245°, 52%, 39%) 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

Sooty
adjective

Old English sōt, soot — adjectival suffix -y. As a color modifier, sooty implies the deep-matte-black quality of multi-decade chimney-and-furnace soot-and-creosote-residue surfaces, the Brontë-period Yorkshire-cottage hearth-and-flue patina. Sits at the deep-and-warm end of the grid, parallel to smoky and pitchy.

Pasqueflower
noun

Eurasian Pulsatilla vulgarisEaster flower in Old English from its mid-spring Pasch / pascha (Easter) blooming season across European chalk grassland. Pasqueflower color refers to a fully opened Pulsatilla vulgaris sepal-cup: a saturated, slightly cool deep blue-violet with the silky finish of long-haired sepals around a yellow-stamened center. The plant is the floral emblem of South Dakota.
