Stripped Saint-Petersburg

#185484
Notes

Stripped Saint-Petersburg (#185484) is a deep azure 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 (207°, 69%, 31%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Stripped
adjective

Old English stripian, to strip — past-participle of strip. As a color modifier, stripped implies a clear-and-bared-and-unornamented quality, the crisp color of Cistercian-and-Bauhaus anti-ornamental stripped-down architectural interior. Sits at the crisp-and-stripped end of the grid, parallel to spare and bare in usage.

Saint-Petersburg
noun

The Russian Baltic city founded by Peter the Great — and the deep blue of the Neva River, the Hermitage Imperial palace's Catherine Hall, and the Imperial Navy uniforms based here. Saint-Petersburg color refers to a Catherine Hall blue-and-gold interior: a saturated, slightly cool deep blue with the matte finish of distemper-painted plaster.
