Senatorial Modré

#235ab9
Notes

Senatorial Modré (#235AB9) 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 (218°, 68%, 43%) 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

Senatorial
adjective

Latin senātōrius, of the senator — adjectival suffix. As a color modifier, senatorial implies a saturated-and-aristocratic-and-Roman-Republic quality, the deep-rich color of Roman-Senate toga praetexta purple-bordered ceremonial-citizen-class livery. Sits at the bold-and-aristocratic end of the grid, parallel to patrician and imperial.

Modré
noun

The Czech word for blue — used for the saturated deep blue of Czech traditional Modrotisk (blue-print) folk-textile resist-dyeing. Modré covers the entire blue spectrum in Czech color vocabulary. The color refers to a freshly Modrotisk-printed cotton: a saturated, slightly cool deep blue with the matte finish of plant-dyed-resist-printed cotton.
