Hardy Loropetalum

#6544d1
Notes

Hardy Loropetalum (#6544D1) is a true indigo 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 (254°, 61%, 54%) 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

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.

Loropetalum
noun

Asian Chinese fringe flower (Loropetalum chinense var. rubrum) — an evergreen shrub native to southern China cultivated worldwide for its strap-like fringed flowers and burgundy foliage. Loropetalum color refers to a L. chinense flush of fringed flowers on burgundy foliage: a saturated, slightly cool deep blue-violet with the velvet finish of dense ribbon-petal flowers. The genus name combines Greek loros (strap) and petalon (petal).

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.
