Refreshing Creek

#64a36c
Notes

Refreshing Creek (#64A36C) is a true green with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (128°, 26%, 52%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Refreshing
adjective

Old French refreschir, to make fresh again — present-participle of refresh. As a color modifier, refreshing implies a clear-and-cool-and-revitalizing quality, the crisp color of Cornish-coast and Hebridean-island fresh-sea-air-and-cool-water revitalization. Sits at the crisp-and-cool end of the grid, parallel to fresh and bracing in usage.

Creek
noun

A small flowing waterway — slightly larger than a brook in American usage, slightly smaller in British. Creek color refers to a typical American Appalachian creek in summer: a soft, slightly cool deep blue-green with the optical clarity of slow-flowing forest stream.
