Open Wedgwood

#3664ad
Notes

Open Wedgwood (#3664AD) 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 (217°, 52%, 45%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Open
adjective

Old English open, unobstructed — used as a color modifier since the eighteenth century for hues that read as airy or uncrowded. Open blue, open green: moderate saturation combined with optical spaciousness, the slight visual breath of a hue that doesn't crowd the surface it covers. Sits at the crisp-bucket center alongside clear.

Wedgwood
noun

The English potter Josiah Wedgwood (1730–1795), whose pale-blue jasperware with applied white classical reliefs became the defining luxury ceramic of late Georgian Britain. The color refers to a piece of unglazed Wedgwood jasper: a soft, slightly muted pale blue with the matte finish of a stoneware body colored by cobalt salts. Lighter than periwinkle, cooler than wedgwood-the-blue's later imitations, with the institutional weight of a brand that's been continuously produced for 250 years.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
