This book is gray
(Book)

Gray just wants to be included. But the other colors are always leaving him out. So he decides to create his own project: an all-gray book. Once upon a time, there lived a wolf, a kitten, and a hippo... Gray just knows it's going to be perfect. But as he adds page after page, the Primary and Secondary colors show up...and they aren't quite so complimentary. A book within a book, this colorful tale explores the ideas of fitting in, appreciating others, and looking at things from another perspective and also uses personality and wit to introduce basic color concepts.--
