Caliginous Gabardine

#01348e
Notes

Caliginous Gabardine (#01348E) 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°, 99%, 28%) 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.

Gabardine
noun

A tightly woven worsted-wool twill — invented by Thomas Burberry in 1879 — used for the original Burberry trench coat and military waterproof outerwear. Gabardine color refers to a classic Burberry-blue gabardine: a soft, slightly cool deep blue-gray with the matte finish of tightly woven twill.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
