Hardy Chicory

#1556c9
Notes

Hardy Chicory (#1556C9) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (218°, 81%, 44%) 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

Hardy
adjective

Old French hardi, bold / brave — past-participle of hardir (to make brave). As a color modifier, hardy implies a saturated-and-cold-resistant quality, the deep-rich color of Scandinavian-and-Russian boreal-forest-and-tundra outdoor-clothing. Sits at the bold-and-resilient end of the grid, parallel to tough and resilient.

Chicory
noun

Cichorium intybus, the European herb whose deep-blue daisy flowers open at dawn and close by midday — and whose roots are roasted as a coffee substitute (café avec chicorée). Chicory color refers to a fresh chicory flower at sunrise: a saturated, slightly cool deep blue with the matte finish of multi-rayed composite flower.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
