I think this song is directed to some who she was friends with before she became famous. "Green to yellow.." they were envious of her record deal and her talent, and then they got sick of seeing her. Maybe because every time they see her on TV, on a magazine cover, they're reminded of what could've been theirs, or who could've been their friend if they hadn't been so jealous. Just my interpretation.
