Even Galway

#51dce4
Notes

Even Galway (#51DCE4) 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 (183°, 73%, 61%) 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

Even
adjective

Old English efen, flat, equal — used as a color modifier since the medieval period for hues that read as uniformly distributed across a surface. Even gray, even tan: the implication is moderate saturation combined with optical uniformity. Sits at the crisp-bucket center alongside steady and balanced.

Galway
noun

The western Irish county — and the deep blue of Galway Bay and the saturated blue of the Aran Islands-and-Cliffs of Moher coastline. Galway color refers to Galway Bay at midday: a saturated, slightly cool deep blue with the optical depth of cold Atlantic-Irish coastal water.
