Looming Marinaro

#0b3f90
Notes

Looming Marinaro (#0B3F90) 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°, 86%, 30%) 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

Looming
adjective

Middle English lomen, to appear vaguely — present-participle of loom. As a color modifier, looming implies a deep-and-vague-and-imposing quality, the dark cool-gray of fog-veiled-and-distant cliff-or-mountain-mass against the sky. Sits at the deep-and-imposing end of the grid, parallel to imposing and towering.

Marinaro
noun

The Italian word for sailor or of the sea — used for the deep blue of marinaro Italian sailor stripes (maglia marinara) and the saturated blue of Italian sailing-club ceremonies. The color refers to an Italian marinaro striped jersey: a saturated, slightly cool deep blue with the matte finish of dyed cotton-and-wool.

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.
