Worn Pool

#638891
Notes

Worn Pool (#638891) is a true 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 (192°, 19%, 48%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Worn
adjective

The past participle of wear — used as a color modifier since the medieval period for hues that have aged through use. Worn leather, worn linen: low saturation combined with the slight optical irregularity that comes from a surface used over years. Sits at the hushed-bucket alongside faded and weathered.

Pool
noun

A constructed body of water — the residential or municipal swimming pool, almost universally lined with white plaster or pale tile that filters the water's color toward blue-green. The color refers to a sunlit pool at noon: a clean, slightly green-shifted light blue with the optical density of chlorinated water in a treated basin. Cooler than aqua, warmer than turquoise, with the suburban weight of mid-century leisure.
