Sinewy Mistral Brick

#a12f20
Notes

Sinewy Mistral Brick (#A12F20) 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 (7°, 67%, 38%) 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

Sinewy
adjective

Old English sinu, sinew — adjectival suffix -y. As a color modifier, sinewy implies a saturated-and-muscular-and-firm quality where the hue carries the lean-and-strong visual presence of a Roman-statue athletic figure. Sits at the bold-and-firm end of the grid, parallel to stalwart and rugged in usage.

Mistral
modifier

Provençal mistral, cold-northwest-wind-of-Provence. As a color modifier, mistral implies a cold-Provençal-and-Rhône-Valley-wind quality, the visual register of Provençal-and-Rhône-Valley-mistral hand-cold-Provençal-and-Rhône-Valley-wind Provençal-and-Rhône-Valley-mistral-and-Alpilles mistral-and-cold-Provençal-and-Rhône-Valley-wind surfaces under Provençal-and-Rhône-Valley-mistral-and-Alpilles Avignon-and-Saint-Rémy-and-Camargue cold-Rhône-Valley-wind-light. Sits at the modifier-and-weather end of the grid, parallel to sirocco and gust in usage.

Brick
noun

Fired clay, mineral red. The color refers to common building brick — iron-rich earthenware kilned to the specific dusky red-orange of a Victorian terrace, a Roman aqueduct, an adobe wall in New Mexico. Less saturated than ruby, warmer than burgundy, with a chalky cast that reads as architectural rather than decorative.
