Robust Cinnamon

#b1520a
Notes

Robust Cinnamon (#B1520A) is a true orange with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (26°, 89%, 37%) 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 azure. 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.

Cinnamon
noun

The inner bark of Cinnamomum verum, the Sri Lankan true cinnamon — harvested in thin scrolls and dried into the curled quills familiar from spice shelves. The color is freshly ground cinnamon powder: a warm, slightly dusty red-brown that sits between rust and cocoa. Warmer than walnut, drier than caramel, with the resinous warmth of a spice that has driven trade routes since the Roman Empire.
