Forceful Murasaki

#912699
Notes

Forceful Murasaki (#912699) is a true violet with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (296°, 60%, 37%) 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.

Murasaki
noun

Japanese 紫, purple — historically the noble color of the Heian-period imperial court, derived from Lithospermum erythrorhizon (gromwell) root dye. Murasaki color refers to a Heian-period court silk kinu robe: a saturated, slightly cool deep violet with the silk luster of multi-bath gromwell-root dye.
