Hardy Fur Brick

#871e01
Notes

Hardy Fur Brick (#871E01) is a deep red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (13°, 99%, 27%) places it in the highly saturated band at a dark 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 cyan. 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.

Fur
modifier

Old French forrer, to-line-with-fur. As a color modifier, fur implies a soft-pelt-and-mammal-coat quality, the visual register of Russian-and-Canadian-fur hand-trapped-and-prepared mink-and-sable-and-fox Russian-and-Canadian-fur-coat-and-trim surfaces under Russian-and-Canadian hand-trapped-fur-coat-and-trim atelier light. Sits at the modifier-and-texture end of the grid, parallel to pelt and fluff in usage.

Brick
noun

Fired clay, mineral red. The color refers to common building brick — iron-rich earthenware kilned to the specific dusky red-orange of a Victorian terrace, a Roman aqueduct, an adobe wall in New Mexico. Less saturated than ruby, warmer than burgundy, with a chalky cast that reads as architectural rather than decorative.

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.

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.
