Spartan Coquelicot

#ad2703
Notes

Spartan Coquelicot (#AD2703) is a true 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°, 97%, 35%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Spartan
adjective

Greek Spartiátēs, of Sparta — adjectival suffix referring to the Lacedaemonian warrior city. As a color modifier, spartan implies a saturated-and-disciplined-and-formal quality, the deep-rich color of Spartan-hoplite military-class crimson-and-bronze armor-and-cloak. Sits at the bold-and-formal end of the grid, parallel to austere and stern in tone.

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.
