Color her bad. Dixie Chicks banjoist Emily Robison recently hopped on the brunet bandwagon alongside Gwynie and Cameron, first hatching her new look at the Grammys. And it’s a move that’s raised quite a ruckus. Postings on the country phenoms’ official website are cautiously positive (”It’s something we have to adjust to,” advises Cowgerl 23). But a prankster at Dallas’ country station 99.5 The Wolf sprayed Robison’s hair hot pink on a local billboard. John Barrett, who owns a salon in New York City’s Bergdorf Goodman, calls the new shade ”a strikeout.” Chicks hairstylist Melanie Shelley insists Robison went au naturel (with store-bought color, no less) ”so she could be herself” during the group’s recent hiatus. An added perk: ”She gets so much respect since she’s gotten so dark.” Sounds like something any country girl would dye for.
