Refreshing Baltic

#57e5f0
Notes

Refreshing Baltic (#57E5F0) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (184°, 84%, 64%) places it in the highly saturated band at a mid 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.

Baltic
noun

The northern European brackish sea between Scandinavia and the European mainland — the source of Baltic amber and the route of medieval Hanseatic League trade. Baltic color refers to mid-depth Baltic water at the Helsinki archipelago: a saturated, slightly cool deep blue with the optical complexity of low-salinity high-latitude inland sea.
