Violet Fairy

Origin
Andrew Lang's Fairy Books — also known as Andrew Lang's "Coloured" Fairy Books or Andrew Lang's Fairy Books of Many Colors — are a series of twelve collections of fairy tales, published between 1889 and 1910. Each volume is distinguished by its own color. In all, 437 tales from a broad range of cultures and countries are presented.

Although Lang only ever used color as a distinction for the title of the book, the titles have been given characteristics of their own over the years and used as stock characters (most recently by Disney).
