Navy blue is a blue so inky it almost appears black. The combination of dark blue and white white was worn by the British Royal Navy in 1748, and thereafter adopted by navies around the world.

Originally called marine blue, navy blue caught the public imagination.

Navy blue is most often seen on blazers kept on reserve at fancy restaurants, yachting, and on sport coats during mandatory private school meetings.
