Readers will love learning their colors with this brightly illustrated, cumulative picture book by bestselling author Audrey Wood and her dynamic, digital-artist son, Bruce. Starting with a rock, a red rock, in the middle of the deep blue sea, the story takes a closer look at this tropical locale. The simple, repetitive text makes for a fun read-aloud for storytime or sharing, and identifying the vivid images and strong colors provides an exciting concept learning experience for young readers. Children can learn their colors as they read about a single green tree joined by a brown nut, a purple parrot, an orange butterfly, a group of singing fishies, and more. It all takes place on a red rock brimming with activity in the deep blue sea!
