Regal Coquelicot

#a53e47
Notes

Regal Coquelicot (#A53E47) is a true red with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (355°, 45%, 45%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Regal
adjective

Latin rēgālis, kingly — derived from rēx (king). As a color modifier, regal implies a saturated-and-royal-formality quality, the deep-rich color of British-Coronation-period royal vestment-and-mantle and Imperial-State-Crown regalia. Sits at the bold-and-imperial end of the grid, parallel to sovereign and royal in usage.

Coquelicot
noun

The French word for poppyPapaver rhoeas — the wild red flower of European cereal fields and the unifying flower of French Impressionist painting (especially Monet's Coquelicots, Argenteuil). The color refers to a freshly opened poppy in a Provençal field: a saturated, slightly cool red with the satin finish of single-day petal. Brighter than scarlet, slightly cooler than tomato.
