Possibly it belonged to a dancer? Because apparently "Dance is a very powerful drug which, if embraced judiciously, it can exorcise demons, access deep seated emotions and color your life in joyous shades of brilliant magenta that you never knew existed."

(Marilyn Hotchkiss's Ballroom Dancing and Charm School. Good Carlyle movie. And it's now what I think of every time I use the word magenta.)
