Towering Samarkand

#401883
Notes

Towering Samarkand (#401883) is a deep indigo 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 (262°, 69%, 30%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Towering
adjective

Old French tour, tower via Latin turris — present-participle of tower. As a color modifier, towering implies a deep-and-vertical-and-architectural quality, the dark cool-gray of Salisbury-Cathedral-and-Chartres-Cathedral spire-and-tower against the sky. Sits at the deep-and-architectural end of the grid, parallel to imposing and looming.

Samarkand
noun

Central Asian Silk Road city in Uzbekistan — capital of Tamerlane's Timurid empire and home of the Registan madrasa complex with its iconic deep-blue tilework. Samarkand color refers to the deep-blue muqarnas vault of the Registan's Tilya-Kori madrasa: a saturated, slightly cool deep blue-violet with the glossy finish of cobalt-and-lazurite-glazed kashin tiles. Slightly warmer than Bukhara.
