Bright Cancún

#66f6c3
Notes

Bright Cancún (#66F6C3) is a true teal with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (159°, 89%, 68%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bright
adjective

Old English beorht, shining, luminous — cognate with the German Bracht, splendor. Applied to color since at least the medieval period for hues that read as luminous: not just light in value but optically active, as if scattering more light back than a dimmer color of the same lightness would. Sits at the bright-bucket center alongside vivid and brilliant.

Cancún
noun

The Mexican Yucatán resort city — and the saturated blue-green of Cancún's Caribbean beach water at Playa Delfines. Cancún refers to the lagoon water at midday: a saturated, slightly cool deep blue-green with the optical clarity of warm Caribbean water filtered through fine quartz sand.

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.
