In the beginning of the film, all of the characters (except Mo) are seen wearing some aspect of orange or purple. Mo is seen wearing blue, which matches her boyfriend. As the film progresses, Mo gradually changes to purple and orange clothing. This symbolizes how although orange and purple are opposites, they complement each other to form the perfect balance. The director uses this tactic to display the same idea with the band.
