Easy Curaçao

#1f90c9
Notes

Easy Curaçao (#1F90C9) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (200°, 73%, 45%) 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

Easy
adjective

Old French aisié, comfortable, at rest — used as a color modifier since the eighteenth century for hues that read as visually undemanding. Easy beige, easy gray: moderate saturation combined with optical restfulness. Sits at the crisp-bucket center alongside calm and settled.

Curaçao
noun

The Caribbean liqueur made from the dried peel of the Citrus aurantium currassuviensis (Laraha orange) — produced on the Dutch Caribbean island of Curaçao since 1896. Blue Curaçao refers to the artificially-colored bright blue variant: a saturated, slightly cool electric blue with the optical clarity of citrus liqueur.
