This book is great for teaching kids about colors in art. They learn about contrasting colors and color opposites. It would be great for an elementary art classroom or any one who wants to teach young kids about colors. I have read the book many times to groups of kids ranging from 2+ to 7. I've found that age 5+ works the best, since it does require that the kids follow some directions for seeing the contrasting colors. However, this book does not focus on reading.
