Gladiatorial Vladivostok

#216cca
Notes

Gladiatorial Vladivostok (#216CCA) 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 (213°, 72%, 46%) 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 orange. 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.

Vladivostok
noun

The Russian Pacific Far East port city — and the saturated deep blue of Amursky Bay and Vladivostok Harbor on the Sea of Japan. Vladivostok refers to the harbor water at midday: a saturated, slightly cool deep blue with the optical depth of cold-water Pacific port.

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.
