Gladiatorial Adonis

#c53022
Notes

Gladiatorial Adonis (#C53022) 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 (5°, 71%, 45%) 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

Gladiatorial
adjective

Latin gladiātōrius, of the gladiator — adjectival suffix, derived from gladius (short-sword). As a color modifier, gladiatorial implies a saturated-and-combative-and-bloody quality, the deep-rich color of Roman-Colosseum gladiator-arena bloody-tunic-and-shield combat-attire. Sits at the bold-and-formal end of the grid, parallel to spartan and valiant.

Adonis
noun

Adonis annua, the small wild buttercup of European meadows — also called pheasant's eye — with single deep red flowers and dark centers. Named for the Greek mythological youth whose blood, in Ovid's telling, sprouted the flower. The color refers to a fresh Adonis bloom in late spring: a saturated, slightly cool deep red with the matte finish of a six-petaled wild flower. Deeper than coral.

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.
