Imperial Salvia
Imperial Salvia (#684BA3) is a true indigo with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (260°, 37%, 47%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
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.
The genus Salvia — the sages of the kitchen and ornamental sages of the garden — over 900 species, many with vivid blue-violet flower spikes that distinguish ornamental cultivars from culinary forms. The color refers to a fresh Salvia farinacea (mealy-cup sage) spike: a saturated, slightly violet-shifted blue with the matte finish of small lipped flowers along a single stem. Cooler than veronica, warmer than larkspur.
