 The production designer, John Muto (qv), used what he describes a  "comic book" sensibility for the film. Characters were given  specific colors, with the bad guys in blues and grays and the girls  in colors. Reginas colors were deeper than Sams to reflect that  Regina was more intellectual than Sam and that Sam was wackier than  Regina. For example, Sams cheerleading outfit is made in magenta  and turquoise to make it really stand out.
