Refreshing Baltic

#378e97
Notes

Refreshing Baltic (#378E97) 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 (186°, 47%, 40%) 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 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.
