Composed Sienna
Composed Sienna (#B74A0C) 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 (22°, 88%, 38%) 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
The past participle of compose, to arrange together — used as a color modifier for hues that read as deliberate and balanced. Composed black, composed gray: the saturation is moderate, the hue is calmly positioned without aggression. Sits at the bold-and-quiet edge of the grid near settled and resolute.
Named for the Tuscan city of Siena, which lent its name to the iron-rich earth pigment ground from local clay since the Renaissance. Raw sienna is a warm yellow-brown; burnt sienna is the same earth fired in a kiln to a deeper red-orange. The color refers to the burnt form: a warm, dusty orange with the matte finish of mineral pigment, used in Florentine fresco and oil painting alike.
