The yellow belly of a toothy green crocodile, the gold in Nefertiti's headdress, the blue water of the Nile—Amy Mullen's sweetly simple designs in this board book are meant to help prereaders learn their colors while also letting them dip a toe into the history and culture of ancient Egypt. Covering many classic images from the land of the pharaohs, here too are a brown pyramid, a black scarab beetle, green papyrus plants, red clay pottery, and a mummy wrapped in white bandages.
