A curious owl stays awake all day long and is astounded at all the colors she sees. Day dawns to a pink sky, fading to bright blue with fluffy white clouds and a yellow sun. The owl notices that the leaves on her tree are green and sees red butterflies land on orange flowers. Gray clouds bring showers, but the sun and rain together produce the most wondrous colors of all—a rainbow. When the day fades into night, the curious little owl remarks about all the beautiful colors there are in the daytime, but still she thinks the nighttime stars are the most wonderful of all. Hopgood’s graphic-design background is evident in his illustrations, which are a mixture of color and texture, painting and drawing, all brought together digitally. The simple text suits this likable story to toddlers and early preschoolers. A solid concept book, but probably without the staying power or punch of Brown Bear, Brown Bear, What Do You See? or Freight Train. (Picture book. 2-5)
