“Blue” by Laura Vaccaro Seeger follows her fabulous picture book “Green.” Unlike the previous color-themed book, “Blue” tells a story about a boy and his dog. The story begins with the color baby blue, a puppy and an infant boy whose blue rattle is cut out in the center; and that blue circle becomes the blue center of a wheel on the little red wagon the young boy is using to take his young dog for a ride.

And as the two grow up together, always in shades of blue, always with cutouts on one page that lead to the next, the scenes vary from ocean blue to sky blue to midnight blue. Always with boy and dog, inseparable.

But blue is at heart a sad color. And the sad truth about loving a dog is that its lifespan is so very short when compared to ours. And a when a young boy and a young dog grow up together, when the boy becomes a teenager, his constant companion, his shadow, his loving confidante, is at the end of his life.

But having loved a dog, truly loved a dog, few choose to remain dog-less for long, and “Blue” is a story not just of love and loss, but of the renewal of love and the rebirth of that loving connection that we feel with our dogs. All in blue. All beautiful.

Each page has a cut-out shape in an object that leads to a different object on the following page. Kids love seeing what happens when the circle cutout depicting a beach ball and a boy in a red shirt becomes a red balloon when the circle opening is now on the red of the boy’s shirt from the previous page. The cutouts and how they are created are brilliant, but so are the many and varied shades and emotions of blue.

Pick this book as a gift for anyone in your life who loves dogs, who loves color, who loves life. Buy it for yourself.
