Zena wakes up to a gray, colorless room and embarks on a journey outside to find the colors.  Each page she comes to is one color whereby kids can name all the things that color.  The book introduces the primary colors first and then the secondary colors.  Each time a new color is introduced, Zena’s hat turns that color, and a polka dot on both her and her dog become that color.  At the end all colors join to become a rainbow.  There is a color wheel activity at the end, which is written for people with absolutely no experience doing art with little kids.  Preschoolers totally enjoyed this book.
