Open Ibiza

#0c589b
Notes

Open Ibiza (#0C589B) is a deep azure with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (208°, 86%, 33%) places it in the highly saturated band at a dark 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Open
adjective

Old English open, unobstructed — used as a color modifier since the eighteenth century for hues that read as airy or uncrowded. Open blue, open green: moderate saturation combined with optical spaciousness, the slight visual breath of a hue that doesn't crowd the surface it covers. Sits at the crisp-bucket center alongside clear.

Ibiza
noun

The Balearic Spanish island — and the saturated blue of Ibizan beach water at Ses Salines and Cala Comte. Ibiza color refers to the cove water at Cala Comte at sunset: a saturated, slightly cool deep blue with the optical depth of warm Balearic Mediterranean water.
