This book is from the Lightning Bolt series, Colors Everywhere. The focus of this book is on the color, blue. The first chapter is on the relaxing world of blue and all the blue things one can find in the world (flowers, jeans, water and sapphires). Next, the book discusses the hues of blue. There is light blue, navy, turquoise, and periwinkle. There is also a chapter about feeling blue and what that means, like singing the blues. There is a chapter about a little girl whose favorite color is blue. At the end of the book, there is a neat activity page about blending colors, followed by a glossary, further reading and index. The pictures in this book are really high quality and I like the easy reading. The layout is nice and attractive. I would like to have the entire set. Children will enjoy it.
