Sure Galway

#408286
Notes

Sure Galway (#408286) 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 (183°, 35%, 39%) 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

Sure
adjective

Old French seur, certain — used as a color modifier since the medieval period for hues that read as confident and stable. Sure red, sure blue: moderate saturation combined with optical commitment. Sits at the crisp-bucket center alongside steady and true.

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.
