Imperial Raspberry

#b91c4b
Notes

Imperial Raspberry (#B91C4B) 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 (342°, 74%, 42%) 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 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.

Raspberry
noun

Rubus idaeus, the European raspberry — its name traces to Mount Ida in either Crete or Anatolia, where the fruit was first described in classical literature. The color refers to a ripe raspberry's drupelets: a saturated, slightly cool deep red-pink with the optical complexity of a hundred-cell aggregate fruit. Cooler than coral, warmer than fuchsia, with the orchard-and-jam weight of a fruit whose color is identical to the food-coloring industry's raspberry red.
