Bright Khorasani

#a66ffa
Notes

Bright Khorasani (#A66FFA) is a soft indigo 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 (264°, 93%, 71%) places it in the highly saturated band at a light lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Bright
adjective

Old English beorht, shining, luminous — cognate with the German Bracht, splendor. Applied to color since at least the medieval period for hues that read as luminous: not just light in value but optically active, as if scattering more light back than a dimmer color of the same lightness would. Sits at the bright-bucket center alongside vivid and brilliant.

Khorasani
noun

Persian خراسانی, Khorasani-style — the long-historical Iranian region of Khorasan whose Safavid-period silk weavers produced the deep-purple imperial textiles for the Mughal courts of India. Khorasani color refers to a Safavid Khorasan-school silk qaba coat: a saturated, slightly cool deep violet with the silk luster of multi-bath gromwell-root-and-indigo overdye on woven Iranian silk.
