Assured Hvar

#01579d
Notes

Assured Hvar (#01579D) 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 (207°, 99%, 31%) 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.

Hvar
noun

The Croatian Adriatic island — and the saturated blue of Hvar's lavender fields, Pakleni Islands archipelago waters, and Stari Grad harbor. Hvar color refers to the lagoon between Hvar and Pakleni: a saturated, slightly cool deep blue with the optical clarity of cold Adriatic water.
