Teenage Room Ideas?!!?

I'm redoing my daughters room. She is 16 years old and currently has a hot pink room. She thinks it's kind of young for her. She can't decide between an ocean blue or green and do an ocean summer theme. Or a light soft pink and do a teen girly chic theme. If you have any suggestions on what to do or other ideas on colors and themes they would be GREATLY appreciated. Feel free to add any pictures of accessories and or colors! Thank you so very much for the help!!
