A beautiful picture book about a little pup's colorful journey through the range of his emotions!

A bright yellow bird promises to bring adventure to sleepy Pup's gray world. As Pup follows his new friend on a walk, each discovery ignites a new feeling and corresponding color, until Pup is saturated with them. But when a storm comes, Pup's color is drained as fear sweeps through him. Only his curious yellow friend remains bright, and encourages him to keep his chin up, play, and carry on!

This is a remarkably simple and resonant examination of exploration and resilience, and introduces the idea of abstract association.
