Asked by Billboard
about the meaning behind her dance in the video, Ziegler replied:
"The story that I was telling in 'Rainbow' was that in the beginning I was discouraged, because there was no rainbow, and I lost all of my magic, and I just kind of felt defeated. And then I finally see a spark, start to believe in myself, and I finally realize that everything is okay -- and if I keep believing in myself, then everything will work out perfect. 'Cause that's when the rainbow comes out, and I was super happy because I feel like all of my magic has come back. Basically, this is all about making your dreams come true, and having that passion and believing in yourself."
