Gladiatorial Ergo Royal

#1d5fc2
Notes

Gladiatorial Ergo Royal (#1D5FC2) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (216°, 74%, 44%) 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 amber. 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.

Ergo
modifier

Latin ergo, therefore-or-thus. As a color modifier, ergo implies a Latin-logical-and-cogito-ergo-sum quality, the visual register of Cartesian-cogito-ergo-sum hand-Latin-logical-and-cogito-ergo-sum Cartesian-cogito-ergo-sum-and-Scholastic-syllogism ergo-and-Latin-logical-and-cogito-ergo-sum surfaces under Cartesian-cogito-ergo-sum-and-Scholastic-syllogism Sorbonne-Scholastic-and-Cartesian-meditation logical-deduction-light. Sits at the modifier-and-Latin end of the grid, parallel to ipse and opus in usage.

Royal
noun

The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.

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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
