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 the British queen Charlotte of Mecklenburg-Strelitz.
Traditionally, dictionaries define royal blue as a deep to dark blue, often with a purple or faint reddish tinge.
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.
Queen blue is a medium tone of royal blue.
The first recorded use of queen blue as a color name in English was in 1926. Before that, since 1661, this color had been called queen’s blue.
