The color has been widely referenced as a characterization, the colour of key plot objects, or as flavor text in many works: Heliotrope was a popular colour reference of Ray Galton and Alan Simpson, script writers of Hancock's Half Hour. In James Joyce's Finnegans Wake, "heliotrope" is the answer to the Maggies' riddle.[clarification needed] Throughout the chapter, the word "heliotrope" is disguised a number of times, hidden either in anagrams, riddles, puns, or obscure allusions. In Harry Potter and the Deathly Hallows, the Polyjuice Potion brewed in order to disguise Hermione Granger as Mafalda Hopkirk is described as having a "pleasant heliotrope colour."
