Antiquated Stockholm

#3a5555
Notes

Antiquated Stockholm (#3A5555) is a deep cyan 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 (180°, 19%, 28%) places it in the muted 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Antiquated
adjective

Latin antīquātus, made old — past-participle of antiquate. As a color modifier, antiquated implies a hushed-and-old-fashioned-and-faded quality where the hue carries the visual register of Edwardian-period faded-and-out-of-fashion period-correct color. Sits at the hushed-and-aged end of the grid, parallel to vintage and antique in usage.

Stockholm
noun

The Swedish capital — and the deep blue of the Stockholm archipelago (24,000 islands) lagoon water and Drottningholm Palace azure interiors. Stockholm color refers to mid-depth Baltic archipelago water at Sandhamn: a saturated, slightly cool deep blue with the optical depth of cold-temperate brackish water.
