Nymphadora Tonks made her first appearance in Harry Potter and the Order of the Phoenix and we later learn that she has a romantic interest in one of the other major, and older, characters. Tonks is a powerful member of the order as she is also a trained and gifted Auror. She is also young and more bubbly than the rest of the members. In book 5 she enjoys making the kids laugh thanks to her abilities as an Metamorphmagus; she can transform her looks at will. The book describes her as having pink hair, though the set picture shows that Warner Bros went with purple instead.
Or did she just change it to purple?
