At the very least, it's one old-timey dress away from being a great cover for a fantasy novel.

Little girl and rainbow
"Look, over there! It's a really great picture of a little girl with a rainbow!" (via attndef on Imgur)

If I was making a book called Look at These Sweet F*cking Rainbows, I'd put a lot of the classics in. You know, quadruple rainbow, screenshots from the double rainbow guy, etc. But I would also add this joyful rainbow picture, taken over the weekend. 

Here's what attndef, the user who posted the image, said on Imgur:

A few minutes ago, I ran outside to take a picture. My daughter chased after me. I told her to go back inside because she was in her pajamas and didn't have any shoes on. She didn't listen. I'm glad she didn't listen.
