Centered Naval

#123f9b
Notes

Centered Naval (#123F9B) 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 (220°, 79%, 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

Centered
adjective

Latin centrum, center — past-participle of center. As a color modifier, centered implies a saturated-and-grounded-and-balanced quality where the hue occupies the visual center of its palette without drift. Sits at the bold-and-balanced end of the grid, parallel to poised and grounded.

Naval
noun

Of the navy — the seagoing branch of a national military. Naval blue refers to the working color of warship paint and naval-shipyard equipment: a slightly muted very deep blue with the matte finish of marine enamel. Deeper than navy (the dress color), cooler than ocean, with the operational specificity of a color used to make a ship harder to spot at distance against North Atlantic water.
