Cleansed Reservoir

#258bc7
Notes

Cleansed Reservoir (#258BC7) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (202°, 69%, 46%) 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

Cleansed
adjective

Old English clǣnsian, to make clean — past-participle of cleanse. As a color modifier, cleansed implies a clear-and-purified quality where the hue has been stripped of any contaminating tint. Sits at the crisp-and-clear end of the grid, parallel to fresh and pristine 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.
