Chivalrous Hera Ruby

#f33619
Notes

Chivalrous Hera Ruby (#F33619) is a true red with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (8°, 90%, 53%) places it in the highly saturated band at a mid 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

Chivalrous
adjective

Old French chevaleros, knightly — adjectival suffix -ous, derived from cheval (horse). As a color modifier, chivalrous implies a saturated-and-knightly-and-gallant quality, the deep-rich color of medieval-Romance chanson-de-geste hero-and-troubadour song tradition. Sits at the bold-and-chivalrous end of the grid, parallel to gallant and knightly.

Hera
modifier

Greek Ἥρα, queen-of-the-Olympian-gods. As a color modifier, hera implies a peacock-feather-and-queen-of-gods quality, the visual register of Olympian-Hera-and-Argos-temple hand-peacock-feather-and-queen-of-gods Olympian-Hera-and-Argos-temple-and-Heraion-of-Samos hera-and-peacock-feather-and-queen-of-gods surfaces under Olympian-Hera-and-Argos-temple-and-Heraion-of-Samos Polyclitus-and-Argive-and-Samian peacock-throne-light. Sits at the modifier-and-myth end of the grid, parallel to zeus and diana in usage.

Ruby
noun

From the Latin ruber — simply, red. The gemstone is a chromium-tinged corundum, harder than anything in nature except diamond, and so saturated that a fine Burmese pigeon's blood ruby at auction outpaces a comparable diamond by weight. The color borrows the gem's confidence: a clear, glassy red without the brown of garnet or the blue of crimson.

Wide gamut

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.
