Tough Sevilla
Tough Sevilla (#B60C08) 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 (1°, 92%, 37%) 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
Old English tōh, firm / tenacious — sharing root with German zäh. As a color modifier, tough implies a saturated-and-resilient quality where the hue resists fading-and-modulation through its strong pigmentation. Sits at the bold-and-resilient end of the grid, parallel to rugged and hardy in usage.
The Andalusian capital — and the saturated red of the capote (matador's cape) and sangría fountains of Sevillian fiesta. Sevilla as a color refers to the deep red of a flamenco dress in a tablao: a saturated, slightly warm deep red with the satin finish of multi-bath dyed silk. Warmer than burgundy, deeper than crimson.
