In this whimsical color-theory storybook, friends little blue and little yellow get carried away while playing together. The result is chaotic for them and their families, but in the end the mystery of what happened is solved and the problem easily fixed. I enjoy this creative author's ability to make a story out of what is essentially blobs of paint, and my daughters get to learn about the color-wheel at the same time! This board book edition is a necessity for young ones. I also appreciate the unique color scheme.
