Regal Chiton Crimson

#e03a2d
Notes

Regal Chiton Crimson (#E03A2D) 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 (4°, 74%, 53%) 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

Regal
adjective

Latin rēgālis, kingly — derived from rēx (king). As a color modifier, regal implies a saturated-and-royal-formality quality, the deep-rich color of British-Coronation-period royal vestment-and-mantle and Imperial-State-Crown regalia. Sits at the bold-and-imperial end of the grid, parallel to sovereign and royal in usage.

Chiton
modifier

Greek χιτών, Hellenic-tunic. As a color modifier, chiton implies a Hellenic-tunic-and-pinned-and-pleated quality, the visual register of Hellenic-Doric-and-Ionic-chiton hand-Hellenic-tunic-and-pinned-and-pleated Hellenic-Doric-and-Ionic-chiton-and-Phidias-Parthenon chiton-and-Hellenic-tunic surfaces under Hellenic-Doric-and-Ionic-chiton-and-Phidias-Parthenon Athenian-Acropolis-and-Hellenic-court Hellenic-tunic-light. Sits at the modifier-and-textile end of the grid, parallel to peplos and tunic 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.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

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.
