Royal Zǐ

#a33791
Notes

Royal Zǐ (#A33791) is a true magenta 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 (310°, 50%, 43%) 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

Royal
noun

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.

noun

Chinese 紫, purple — the imperial court color of the Tang and Song dynasties, derived from Lithospermum erythrorhizon (gromwell) and overdyed with Polygonum tinctorium. color refers to a Tang-dynasty imperial robe field: a saturated, slightly cool deep violet with the silk luster of multi-bath gromwell-root-and-indigo overdye on tussah silk. Cooler than zǐsè (formal deep purple).
