Resolute Dew Brick

#900c01
Notes

Resolute Dew Brick (#900C01) is a deep 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 (5°, 99%, 28%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Resolute
adjective

From the Latin resolutus, unwavering — used as a color modifier in literary contexts for hues that read as committed and unmoving. Resolute blue, resolute green: the saturation is full, the hue holds its position without shifting under different light. Sits in the bold-bucket center alongside strong and true, with slightly more focus on stability than presence.

Dew
modifier

Old English dēaw, morning-moisture. As a color modifier, dew implies a beaded-and-fresh-and-morning-moisture quality, the visual register of spider-web-and-meadow-grass-dew hand-beaded-and-pearl-and-morning spider-web-and-meadow-grass-and-petal-edge dewed-and-beaded-and-pearl surfaces under spider-web-and-meadow-grass first-light-of-dawn-and-rising-mist-and-pearl morning-meadow-light. Sits at the modifier-and-mood end of the grid, parallel to mist and gleam 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.
