Gladiatorial Vasilek

#3f7df6
Notes

Gladiatorial Vasilek (#3F7DF6) is a true azure 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 (220°, 91%, 61%) 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 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.

Vasilek
noun

The Russian word for cornflower (Centaurea cyanus) — and the saturated bright blue of cornflower fields among Russian wheat. Vasilek-blue is the unifying field-flower color of Russian rural summer. The color refers to a fresh cornflower at peak bloom in a Russian wheat field: a saturated, slightly cool bright blue.
