Listen here, you chucklehead. You obviously struggle with the subtle beauty of language. Let's break this down like a kid's block tower. You see, a rainbow is a colorful arc in the sky. When we say someone is "scoring with flying colors," we mean they did really good. In the joke, the rainbow is doing well in class, just like they are "scoring with flying colors." It’s funny because it uses the image of a rainbow literally scoring with colors. Get it now, genius?
