Refreshing Surf

#7defea
Notes

Refreshing Surf (#7DEFEA) is a soft cyan 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 (177°, 78%, 71%) places it in the highly saturated band at a light lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

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.

Surf
noun

The white water produced where waves break — bubbles of compressed air carried in shallow water and dispersing as the wave reforms. The color refers to surf retreating across wet sand: a soft, very pale blue-green with the optical brightness of bubble dispersion. Lighter than seafoam, cooler than frost, with the kinetic weight of a color that's never still — every photograph of surf is already obsolete.
