Royal blue
It is said to have been created by a consortium of mills in Rode, Somerset, which won a competition to make a robe for Queen Charlotte, consort of King George III.In winning the prize, a business in the village invented the dye and received a certificate to sell it under that name.[6] US dictionaries give it as further towards purple, e.g. "a deep, vivid reddish or purplish blue" (Webster's New World College Dictionary)[7] or "a vivid purplish blue" (Merriam-Webster).The World Wide Web Consortium designated the keyword "royalblue" to be this much brighter color, rather than the traditional darker version of royal blue.Cree Inc. uses the term Royal Blue to describe light emitting diodes in the wavelength range 450–465 nanometers, slightly shorter than the regular blue range of 465–485 nanometers.
