Patrician Kyomurasaki

#642fa4
Notes

Patrician Kyomurasaki (#642FA4) 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 (267°, 55%, 41%) 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

Patrician
adjective

Latin patrīcius, of the noble class — derived from pater (father). As a color modifier, patrician implies a saturated-and-aristocratic-and-Roman-Republic quality, the deep-rich color of Roman-Patrician-class toga and senatorial-livery hereditary-aristocratic dress. Sits at the bold-and-aristocratic end of the grid, parallel to senatorial and imperial.

Kyomurasaki
noun

Kyoto purple (京紫) — the warmer red-tinted purple of the Heian-period imperial court at Kyoto, distinguished from the cooler Edo-period edomurasaki. Kyomurasaki color refers to a Kyoto-court ceremonial kariginu hunting robe: a saturated, slightly cool deep violet with the silk luster of multi-bath gromwell-root-and-akane (madder) dye on woven silk crepe. Slightly warmer than Edomurasaki.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
