The Color: A grapey purple color, with tones of lavender and lilac, this color is full of magic and mystery.
The Name: Nimue persuaded Merlin to teach her magic and also became his lover. But she betrayed him by imprisoning him in a tree (or cave or tower, depending on the story). Afterwards, she married Pelleas, one of the knights. Her name varies across the stories, including Niniane and Viviane as variants.
