Bulky Pasqueflower

#636aef
Notes

Bulky Pasqueflower (#636AEF) 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 (237°, 81%, 66%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Bulky

Old Norse búlki, cargo / mass — adjectival suffix -y. As a color modifier, bulky implies a saturated-and-massive-and-occupying quality where the hue takes up visual space with broad-and-heavy presence. Sits at the bold-and-weighty end of the grid, parallel to hefty and substantial in usage.

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.
