Raindrops: A Shower of Colors

This cheery book uses animals to show how blending colors creates new ones. Raindrop-shaped die-cut windows hold colored acetate inserts, so the cutout on a robin’s red wing matches a yak’s yellow die-cut, creating an orange window for a goofy orange octopus. In between the color-focused pages, the animals flee a gathering rainstorm: “Go! Go! Go!” Not all cutouts (for a pink pig, black bear, and others) are transparent, leading to some dead ends, in terms of color mixing, but overall it’s a winning visual effect. Ages 3–5. (Apr.)
