Stormy Admiral

#003790
Notes

Stormy Admiral (#003790) 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°, 100%, 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

Stormy
adjective

Old English storm, storm — adjectival suffix -y. As a color modifier, stormy implies a deep-and-turbulent-and-cool-shifted quality, the dark cool-gray of Force-9-gale atmospheric-turbulence sky. Sits at the deep-and-turbulent end of the grid, parallel to thunderous and tempestuous in atmospheric register.

Admiral
noun

The dark blue of a flag officer's dress uniform — particularly the British and American admirals' coats with gold braid and bullion. The color refers to an admiral-rank dress coat: a saturated, slightly muted very deep blue with the matte finish of melton wool dyed to maximum intensity. Deeper than navy, warmer than midnight, with the rank-insignia weight of a color reserved for the most senior naval officers.

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.
