"Let's paint a picture of that cornfield," says Aunt Emily to Patrick, as they sit looking out from the shade of a tree. As Patrick puts a yellow blob on his palette to paint the corn, a red squirrel runs into the field; when he puts down red, a bluebird appears. Each page reveals a new colour and a new creature - until Patrick's palette is filled with colours and the field with animals. This simple story, vividly illustrated, introduces all the basic colours and the concept of colour mixing to very young readers.
