Royal Mauve
Royal Mauve (#9E48C0) is a true violet with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (283°, 49%, 52%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.
The first synthetic aniline dye — an accidental product of William Perkin's 1856 attempt to synthesize quinine, which yielded a stable purple instead. Mauve (French for mallow) became the chemical-industry breakthrough that reshaped textile coloring. The color refers to a freshly mauve-dyed silk: a soft, slightly red-shifted pale purple with the slight luster of synthetic-dyed natural fiber. Lighter than violet, warmer than lilac, with the industrial-history weight of the pigment that founded modern chemistry.
