Thinned Pewter

#91a9b8
Notes

Thinned Pewter (#91A9B8) is a true azure with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (203°, 22%, 65%) places it in the muted 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

Thinned
adjective

Old English thynne, thin — past-participle of thin. As a color modifier, thinned implies a pale-and-attenuated quality, the pale color of Old-Master-and-Modernist studio-paint heavy-medium-thinned glaze-and-tone reduced-pigment surface. Sits at the pale-and-diluted end of the grid, parallel to watery and diluted in usage.

Pewter
noun

An alloy of tin with copper, antimony, and (historically) lead — pre-industrial tableware metal of European households before china replaced it in the eighteenth century. The color refers to a Georgian pewter tankard: a soft, slightly muted gray with the satin finish of a cast and polished alloy. Cooler than bronze, warmer than silver, with the archaic-domestic weight of a metal that aged darker as households used it.
