Foreboding Gabardine

#04376a
Notes

Foreboding Gabardine (#04376A) 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 (210°, 93%, 22%) 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.

Etymology

Foreboding
adjective

Old English fore-bēodan, to announce in advance — present-participle of forebode. As a color modifier, foreboding implies a deep-and-threatening atmospheric-anticipation quality, the dark cool-gray of advancing-cyclone storm-front cumulonimbus-base. Sits at the deep-and-threatening end of the grid, parallel to ominous and menacing in atmospheric tone.

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.
