Imperial Sangiovese

#b73037
Notes

Imperial Sangiovese (#B73037) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (357°, 58%, 45%) 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 cyan. 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.

Sangiovese
noun

The dominant red grape of central Italy — backbone of Chianti, Brunello, and Vino Nobile. The color refers to a young Brunello di Montalcino: a saturated, slightly cool deep red with the optical complexity of well-aged Tuscan wine. Deeper than Chianti, cooler than Tempranillo.
