Country Coke

#21011e
Notes

Country Coke (#21011E) is a deep violet 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 (306°, 94%, 7%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Coke

Coal-coke — the deep-glassy-black solid residue of bituminous-coal pyrolysis in oxygen-poor conditions, the principal industrial-iron-smelting fuel since Abraham Darby's 1709 Coalbrookdale coke-iron breakthrough. Coke color refers to a freshly cooled coke-oven battery in raking light: a saturated, slightly cool deep black with the matte finish of cooling-rate-quenched bituminous-coal pyrolysis residue on industrial firebrick.
