Frayed Pool

#638f94
Notes

Frayed Pool (#638F94) 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 (186°, 20%, 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

Frayed
adjective

Old French froyer, to rub — past-participle of fray. As a color modifier, frayed implies a hushed-and-edge-worn-and-aged quality, the hushed color of multi-decade cuffed-and-collared heavily-worn dress-attire textile-edges. Sits at the hushed-and-worn end of the grid, parallel to threadbare and tattered in usage.

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.
