Steadfast Joy Crimson

#b72222
Notes

Steadfast Joy Crimson (#B72222) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (0°, 69%, 43%) 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

Steadfast
adjective

Old English stede-fæst, fixed in place — sharing root with German stetig. As a color modifier, steadfast implies a saturated-and-unwavering quality where the hue maintains its visual character without modulation. Sits at the bold-and-firm end of the grid, parallel to unwavering and firm in usage.

Joy
modifier

Latin gaudia, delights. As a color modifier, joy implies a bright-and-radiant-and-uplifted quality, the visual register of Provençal-troubadour-and-Florentine-Carnival-joy hand-bright-and-radiant-and-uplifted Provençal-troubadour-and-Florentine-Carnival-and-Renaissance-festa joyful-and-bright-and-radiant-and-uplifted surfaces under Provençal-troubadour-and-Florentine-Carnival-and-Renaissance-festa banner-and-procession-and-piazza festival-day-light. Sits at the modifier-and-mood end of the grid, parallel to bliss and glee in usage.

Crimson
noun

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.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
