Spangled Curaçao

#31e2dd
Notes

Spangled Curaçao (#31E2DD) 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 (178°, 75%, 54%) 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

Spangled
adjective

Middle Dutch spange, clasp / metal-disc — past-participle of spangle. As a color modifier, spangled implies a saturated-and-multi-point-reflective quality, the bright color of American-flag-stars and sequined-fabric metallic-disc-and-jewel-decoration. Sits at the bright-and-reflective end of the grid, parallel to glittering and sequined in usage.

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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
