I think either the blue, turquoise or baby green was my fave. Probs the turquoise. Such a lovely shade. I liked her blue/pink hair during the Timber era, too.
Kesha and a non-vocalist female would slay. Obviously I'm meaning Iggy or Nicki. But I think Kesha and Miley could make a great hoedown throwdown country influenced party track too. Maybe even Taylor Swift on a ballad.
