Navy blue is a very dark shade of the color blue which almost appears as black. Navy blue 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. It was also worn by the Americans during some wars.

When this color, taken from the usual color 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 color soon changed to navy blue.

The first recorded use of Navy blue as a color name in English was in 1840.

Navy blue is used by numerous professional and collegiate sports teams:

Diane Renay (b. July 13, 1945), born Renee Diane Kushner, is an American pop singer, best known for her 1964 hit song, "Navy Blue".

Renay was born to a Jewish family in South Philadelphia, Pennsylvania. She started singing at an early age and took voice lessons from Artie Singer, a voice teacher who also managed Danny and the Juniors (of "At the Hop" fame). Singer encouraged Renay to pursue a recording career. Renay attended Northeast High School (Philadelphia, Pennsylvania).

Record producer/songwriter, Pete DeAngelis was a frequent customer at the Kushners' family jewelry store, and Renay's parents arranged for her to audition for him. DeAngelis, impressed with her talents, got Renay signed to the Atco Records label. Under the new stage name Diane Renay, she released her first single, "Little White Lies", in 1962, but it failed to chart nationally, as did the follow-up, "Tender", and Atco dropped her from the label.

However, Bob Crewe, who had written and produced material for Renay's second recording session, then signed her to a new recording contract whereby he would write and produce records for her. Under Crewe's guidance and signed to the 20th Century label, Renay, then 17 years old, released her biggest hit, "Navy Blue", in late 1963. The song told the story of a girl who was lonely for her steady boyfriend while he was away from home in the U.S. Navy and could hardly wait to see him again. "Navy Blue", which was composed by Crewe with Bud Rehak and Eddie Rambeau, became a national smash, reaching No. 6 on the US Billboard Hot 100 in February 1964, and soaring to No. 1 on the Adult Contemporary singles chart. The song was followed by Renay's debut album, also titled Navy Blue.

In 2001, Rina's first album, "Be Happy", that includes "Koi wa Thrill, Shock, Suspense", was released. Since then, she came to appear on TV, and became very popular in Japan. In 2002, Rina's second album "POWER OF WORDS" was released, and it is the most popular album in her work. "POWER OF WORDS" reached the top of the Oricon charts and sold over 540,000 copies.
