*"Australian author/illustrator Canty builds a conceptual guessing game around the rainbow's seven colors....Canty's illustrations are exquisitely clear, drawing children in first to guess at the silhouetted mystery images, then to linger over the beautifully painted ones. A stellar concept title and a fine choice for both one-on-one and group sharing."--Kirkus Reviews, starred review


The award-winning author/illustrator of the Heads and Tails series introduces readers to a multi-tiered new concept book about shape and color sorting and object identification. With fresh and appealing illustrations and a striking design, this is a concept book with longevity.
