Royal blue is a deep and vivid shade of 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.^[3]
