Royal blue is both a bright shade and a dark shade of azure blue. It is said to have been created by millers in Rode, Somerset, a consortium of which won a competition to make a dress for Queen Charlotte, consort of King George III.
Brightness
Traditionally, dictionaries define royal blue as a deep to dark blue, often with a purple or faint reddish tinge. Oxford English Dictionary defines it as "deep vivid blue".
By the 1950s, many people began to think of royal blue as a brighter color, and it is this brighter color that was chosen as the web color "royal blue" (the web colors when they were formulated in 1987 were originally known as the X11 colors). The World Wide Web Consortium designated the keyword "royalblue" to be this much brighter color, rather than the traditional darker version of royal blue.

In culture
- In auto racing, royal blue (called "imperial blue") is the traditional color of Ford and Carroll Shelby, and for 2012, the primary livery for Hendrick Motorsports' #48 sponsored by Lowe's.
- Royal blue is an official color used in the flags of American Samoa, Cayman Islands, the European Union, Galicia, Georgia, Israel, New Zealand, Texas, Tuvalu, and the United Kingdom.
- The Flag of the Philippines uses a royal blue field, which is normally displayed over the red field, to signify a state of peace. Reversing this arrangement (i.e. red above blue) transforms the flag into the nation’s war ensign.
- When, in 2008, the United States Transportation Security Administration changed the color of airport screener uniforms from white to royal blue, they found that it made the work of the airport screeners easier because airline passengers became more compliant, apparently because by wearing blue, the airport screeners came to be perceived more as authority figures.
