Clean Bergen

#66dee6
Notes

Clean Bergen (#66DEE6) 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°, 72%, 65%) 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.

Bergen
noun

The Norwegian fjord-town on the Bryggen harbor — and the saturated deep blue of Bergen's Vågen harbor and the surrounding Hardangerfjord water. Bergen color refers to Bergen harbor at clear-day midday: a saturated, slightly cool deep blue with the optical depth of glacier-fed coastal water.
