Punchy Rough Cornflower

#6476eb
Notes

Punchy Rough Cornflower (#6476EB) 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 (232°, 77%, 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Punchy
adjective

A modern adjectival form of punch, to strike sharply. Used as a color word since the early twentieth century for hues that read as highly contrasting and visually loud. Punchy red, punchy yellow: the implication is full saturation combined with optical impact. Sits across the bold and bright buckets, near vivid and striking.

Rough
modifier

Old English rūh, rough. As a color modifier, rough implies an unfinished-and-coarse quality, the visual register of unfinished-stone-and-burlap hand-quarried-and-unprocessed coarse-and-unfinished-textile-and-stone hand-quarried-and-coarse surfaces under hand-quarried-and-unfinished workshop-light. Sits at the modifier-and-texture end of the grid, parallel to hewn and bark in usage.

Cornflower
noun

Centaurea cyanus, the small wild blue flower of European cereal fields — once a weed of wheat agriculture, now nearly extinct in the wild after a century of herbicides. The color refers to a fully open cornflower in summer: a saturated, slightly violet-shifted blue with the spiky daisy structure of the Asteraceae. Cooler than periwinkle, warmer than cobalt, with the agricultural weight of a flower whose name is a synonym for blue in the Slavic and German textile trade.

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.
