Murky Marinaro

#153997
Notes

Murky Marinaro (#153997) 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 (223°, 76%, 34%) 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

Murky
adjective

From Old Norse myrkr, darkness — sharing root with mirkwood. Murky implies low value combined with reduced clarity — the deep brown-greens of pond water, the dim interior of a smoke-blackened bar. Sits at the deep-and-dirtied end of the grid, where the color is both dark and slightly clouded.

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.
