Senatorial Mandarino

#b13403
Notes

Senatorial Mandarino (#B13403) 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 (17°, 97%, 35%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Sits at the bold-and-aristocratic end of the grid, parallel to patrician and imperial.

Mandarino
noun

The Italian word for mandarinCitrus reticulata — the small citrus cultivated in Sicily since Arab agricultural-period introduction.
