The favorite childhood I Spy game, in which a child distinguishes items of a particular color in a room or setting, becomes a sturdy photographic book on color identification. Blue, yellow, red, green, and orange come into focus with the opening words, ""I spy with my little eye,"" shown within a circle of everyday objects of the matching color--e.g., a plastic picnic fork, a bathtub toy whale, a pitcher, cup and plate, a block, a ball. A vague clue is given on the facing page, for example, ""something blue and bouncy."" A die-cut ellipse, the shape of an eye, reveals the color and texture of the object; with the turn of the page, the object seen through the cut-out is on display against an appropriate background. A blue ball is found in a shimmering turquoise pool, a yellow bucket sits in the sand at the beach, a green watering can blends in with grass, leaves, and plants in the garden, and more, with an invitation for children to investigate other items of that particular color in the scene. Keen colors along with vignettes of toddlers messily finger-painting in the featured color make this even more accessible to those in the point-and-name stage.
