Stripped Reservoir

#3f90b4
Notes

Stripped Reservoir (#3F90B4) 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 (198°, 48%, 48%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Stripped

Old English stripian, to strip — past-participle of strip. As a color modifier, stripped implies a clear-and-bared-and-unornamented quality, the crisp color of Cistercian-and-Bauhaus anti-ornamental stripped-down architectural interior. Sits at the crisp-and-stripped end of the grid, parallel to spare and bare in usage.

Reservoir
noun

A constructed body of water — particularly the dam-impounded reservoirs of arid-region water supply: Lake Mead, Hetch Hetchy, Lake Powell. Reservoir color refers to mid-depth Lake Mead water: a saturated, slightly cool deep blue with the optical depth of stored desert water.
