Steady Stockholm

#3f90b8
Notes

Steady Stockholm (#3F90B8) is a true azure 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 (200°, 49%, 48%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Steady
adjective

Old English stede, place, position — drifted to mean firm and unmoving. Used as a color modifier since the seventeenth century for hues that read as reliable rather than dramatic. Steady gray, steady green: moderate saturation combined with optical calmness. Sits in the crisp-bucket center alongside settled.

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.
