Forceful Bliss Crimson

#b71d27
Notes

Forceful Bliss Crimson (#B71D27) 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 (356°, 73%, 42%) 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.

As a color modifier, bliss implies a deep-joy-and-rapture-and-contentment quality, the visual register of Beatific-Vision-and-Elysian-Field-bliss hand-deep-joy-and-rapture-and-contentment Beatific-Vision-and-Elysian-Field-and-paradise-meadow blissed-and-deep-joy-and-rapture surfaces under Beatific-Vision-and-Elysian-Field-and-paradise-meadow heavenly-and-rapturous-and-blessed paradise-light. Sits at the modifier-and-mood end of the grid, parallel to joy and mirth 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.
