This is one of the more interesting "colors" books for toddlers, made more fun by the addition of sliding panels that pull out from each page to reveal animals of the featured color. The illustrations are pleasingly bright and simple, and the sliding panels make it quite enjoyable for "reading" alone or with an adult. Toddlers might even learn some colors, although the primary educational experience at this age is what a book is and does.
Unfortunately, while the sliding board book concept is very fun, it is not long-wearing. The panels bend when handled roughly, making them difficult for little hands to get them back into place, and the anchoring pages split when the panels are pulled out too hard. Still, this is wonderful for children who transitioning from the "books are toys" phase into a read-aloud capability.
