Navy blue is a very dark shade of the colour blue.
The colour got its name from the dark blue (contrasted with white) worn by officers in the British Royal Navy since 1748 and subsequently adopted by other navies around the world.
When this colour name, taken from the usual colour of the uniforms of sailors, originally came into use in the early 19th century, it was initially called marine blue, but the name of the colour soon changed to navy blue.
An early use as a colour name in English was in 1840 though the Oxford English Dictionary has a citation from 1813.
