Utilitarian Pool

#1f6665
Notes

Utilitarian Pool (#1F6665) is a deep 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 (179°, 53%, 26%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Utilitarian
adjective

Latin ūtilitās, usefulness — adjectival suffix -ian. As a color modifier, utilitarian implies a clear-and-purpose-fit-and-stripped-down quality, the crisp color of Shaker-and-Quaker anti-ornamental functional-and-no-frills craft tradition. Sits at the crisp-and-functional end of the grid, parallel to functional and workmanlike 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.
