It is so conceptual. In the beginning the world is dark and blue because she is in a truly bad mood.
She goes through the labyrinth and when she meets the girl there is a hint of warmness in the footage because
represents hope. Then the next few parts are the obstacles and the challenges that she faced in the journey,
and when she finally gets out, the world is beautiful and warm representing true happiness.
Then "prince charming" comes along who is deceiving to the viewers but we all know it's Russell.
Oh, and no product placement for such a huge video.
