This book follows the very clever concept of crayons writing protest letters to a young boy which highlight children's tendencies in choosing colors when creating art. White and black raise particularly thought-provoking arguements that could be explored in the art classroom. However, art teacher here disliked the TWO references to coloring within the lines as well as the frequent use of coloring book examples as opposed to free drawing with crayons. Frankly, I would probably "read" those page aloud in my own words when using the book in a classroom.
