Navy blue takes its name from the dark blue (contrasting with navy white) worn by Royal Navy officers from 1748 onward, and later adopted by other navies around the world. When the colour's name, derived from the common colour of sailors' uniforms, came into use in the early 19th century, it was initially called sea blue, but the colour's name was soon changed to navy blue.

Navy blue is a colour that exudes sophistication, strength, and depth.

It is a colour that can convey a sense of calm and stability, as well as authority and power. It is associated with trust, loyalty, and wisdom. It also relates to strong spiritual beliefs, the tradition of the evil eye, and the hamsa hand.

Other shades in this palette include:

Cobalt

Cobalt is associated with stormy skies or the depths of the ocean. It is noble and exclusive. It evokes an impression of extreme elegance, yet at the same time quite calm and harmonious.

Indygo

Indigo is the colour of integrity, structure, intuition, and order.

In interiors, it contrasts well with shades of grey, white, and brown, often used in yacht furnishing styles, the terraces of seaside villas and apartments, and even in more masculine bedrooms.
