Placid Hvar

#66bdfb
Notes

Placid Hvar (#66BDFB) is a true azure 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 (205°, 95%, 69%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Placid
adjective

Latin placidus, gentle / quiet — derived from placēre (to please). As a color modifier, placid implies a clear-and-unruffled quality where the hue carries the visual register of mirror-smooth lake-surface in windless mid-morning. Sits at the crisp-and-calm end of the grid, parallel to serene and peaceful in usage.

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.
