Smoldering Pasqueflower

#584ad0
Notes

Smoldering Pasqueflower (#584AD0) is a true blue with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (246°, 59%, 55%) 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

Smoldering
adjective

The progressive participle of smolder, to burn slowly without flame. Used as a color word since the late nineteenth century for the deep reds and oranges of barely-flame coal — the warm saturated darks where the heat is internal rather than emitted. Sits in the bold-and-warm corner, slightly less luminous than burning and slightly less calm than rich.

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.
