BrightnessEdit

The Oxford English Dictionary defines "royal blue" as "a deep vivid blue",[8] while the Cambridge English Dictionary defined it as "a strong, bright blue colour",[9] and Collins defines it as "a deep blue colour".[10] US dictionaries give it as further towards purple, e.g. "a deep, vivid reddish or purplish blue" (Webster’s New World College Dictionary)[11] or "a vivid purplish blue" (Merriam-Webster).[12]

By the 1950s, many people[who?] 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.
