Imperial Cherry

#a40929
Notes

Imperial Cherry (#A40929) is a deep red 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 (348°, 90%, 34%) places it in the highly saturated band at a dark 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Imperial
adjective

From the Latin imperialis, of the empire — applied to color since the medieval period for the hues reserved for sovereigns and empires: imperial purple of Tyrian dye, imperial yellow of Ming-dynasty porcelain. As a modifier, imperial implies saturation combined with the institutional weight of a color owned by a court. Sits in the bold-and-deep corner, alongside royal.

Cherry
noun

Borrowed into English from the Old North French cherise, the cherry has been a cultivated red since at least the Greek colonies of Pontus on the Black Sea. The color refers specifically to the fruit at full ripeness — a clean, sweet red, brighter than wine and warmer than crimson, somewhere between Prunus avium and the lacquered finish of a Stradivarius.
