Unwavering Brick

#a5351e
Notes

Unwavering Brick (#A5351E) 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 (10°, 69%, 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

Unwavering
adjective

Old English un- (negation) plus wafrian (to flicker). As a color modifier, unwavering implies a saturated-and-constant quality where the hue maintains its full strength without flicker or shift. Sits at the bold-and-firm end of the grid, parallel to steadfast and firm 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
