Tenacious Hewn Crimson
Tenacious Hewn Crimson (#B0061F) 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 (351°, 93%, 36%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin tenāx, holding-fast — adjectival suffix -ous. As a color modifier, tenacious implies a saturated-and-clinging quality where the hue grips its substrate with stubborn pigmentation. Sits at the bold-and-resilient end of the grid, parallel to unyielding and adamant in usage.
Old English hēawan, to-hew. As a color modifier, hewn implies a hand-cut-stone-or-timber quality, the visual register of hand-hewn-stone-and-timber hand-cut-and-shaped stone-and-timber-and-log hand-hewn-construction-and-craft surfaces under hand-hewn stone-and-timber workshop-light. Sits at the modifier-and-texture end of the grid, parallel to carved and cast in usage.
From the Old Spanish cremesin, itself from the Arabic qirmiz — the kermes scale insect, dried and ground into a brilliant carmine dye prized in the medieval Mediterranean. For centuries the most expensive red on a draper's shelf, reserved for cardinals, kings, and the cloth that gave English the word crimson. Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.
