Steady Kattegat

#1d88ba
Notes

Steady Kattegat (#1D88BA) 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 (199°, 73%, 42%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Steady
adjective

Old English stede, place, position — drifted to mean firm and unmoving. Used as a color modifier since the seventeenth century for hues that read as reliable rather than dramatic. Steady gray, steady green: moderate saturation combined with optical calmness. Sits in the crisp-bucket center alongside settled.

Kattegat
noun

The body of saltwater between the Jutland peninsula and southwestern Sweden — separating the Baltic from the North Sea via the Skagerrak. Kattegat refers to mid-depth Kattegat water near Hesselø: a saturated, slightly cool deep blue with the optical depth of brackish Scandinavian water.
