Beautiful. As if you're walking through a portal, picking and choosing the most horrific, terrible, crushing points in your life and tossing them into the wind, to forever be forgotten. You have to put things behind you in order to push on. Iridescent. 'displaying a play of lustrous colors like those of the rainbow' Like a rainbow, we all have our colors, per say. I like to think of this song as a way of telling some one, "You are colorful. You are worth it. Brush yourself off, get up, and make something great with what you've got."
