Caliginous Hvar

#03307c
Notes

Caliginous Hvar (#03307C) 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 (218°, 95%, 25%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Caliginous
adjective

Latin cālīginōsus, misty / dark — derived from cālīgō (mist, gloom). As a color modifier, caliginous implies an obscured, dimmed, slightly-cool-shifted quality where the hue is veiled by darkness or atmospheric fog. Sits at the deep-and-veiled end of the grid, between murky and tenebrous 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.
