Caliginous Antibes

#143c7c
Notes

Caliginous Antibes (#143C7C) 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 (217°, 72%, 28%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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.

Antibes
noun

The French Riviera town between Cannes and Nice — and the saturated deep blue of the Côte d'Azur between Cap d'Antibes and the harbor. Antibes color refers to Cap d'Antibes sea water at midday: a saturated, slightly cool deep blue with the optical clarity of warm Mediterranean coast.
