Each page has a cute little rhyme and features a cheerful array of color-themed animals and flowers. For example, the blue page says "Hurry, cricket,/Join the romp,/Spring brings BLUE - /hope and stomp." The page features some simple blue flowers, a blue cricket, green leaves, a red ladybug, yellow bee, green grasshopper, and orange caterpillar. As the pages progress, they add a bug. So the first page is red with a red ladybug, then orange with an orange caterpillar and the ladybug, all the way up to the final spread with a sixth bug, a purple butterfly.
At the side of the book are two ridged wheels. As you turn them, the colors (a die cut circle in the center of the flowers) change. When the colors are correctly aligned, they match the flower. So, for the orange flower, one wheel is yellow and one red. There are also little dots on the wheels to line up so they completely cover the circle.
With just six spreads, the book is small and compact, the last page being made in several layers to accomodate the wheels. The wheels themselves are very thin, almost cardstock rather than cardboard, but since they're very protected by the book I think they're probably fine. The only drawback is they're difficult to turn separately, since they're so thin and right on top of each other.
Verdict: A fun way to introduce beginning color blending. Recommended.
