Robust Chianti

#cb3228
Notes

Robust Chianti (#CB3228) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (4°, 67%, 48%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Robust
adjective

From the Latin robustus, of oak — implying strength combined with substance. As a color modifier, robust describes saturation combined with body: a robust burgundy, a robust olive. Sits in the bold-and-warm corner alongside strong and solid, with the slightly textural implication of a color that has substance behind the pigment.

Chianti
noun

The Tuscan wine region between Florence and Siena — and the Sangiovese-based reds of Chianti Classico, the gallo nero black-rooster appellation that has marked authentic bottles since 1924. The color refers to a young Chianti Classico in a glass: a saturated, slightly cool deep red with the optical clarity of medium-tannin wine. Lighter than Bordeaux, warmer than Burgundy.
