Wholesome Copenhagen

#42dcec
Notes

Wholesome Copenhagen (#42DCEC) 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 (186°, 82%, 59%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Wholesome
adjective

An adjectival form of whole — used as a color modifier since the sixteenth century for hues that read as healthy and unadulterated. Wholesome cream, wholesome wheat: moderate saturation combined with the optical impression of a natural origin. Sits at the crisp-bucket alongside genuine.

Copenhagen
noun

The Danish capital — and the saturated deep blue of Nyhavn canal water at midday and the Copenhagen Royal Porcelain underglaze produced since 1775. Copenhagen refers to a Royal Copenhagen Blue Fluted underglaze: a saturated, slightly cool deep blue with the high gloss of fired cobalt-on-porcelain.

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.
