Those who think they've seen everything in the ubiquitous color concept-book genre haven't seen Cabrera's debut, an irresistible take on the subject. An orange-and-black kitten takes children on a trip through his world and invites them to discover his favorite color. In a series of involving spreads, the kitten explores the world and introduces both concepts and colors. Each time the kitten asks if a particular color is it, viewers are treated to a boldly gestural, accomplished oil painting in green, pink, black (""the night when bats swoop and soar""), red, yellow, purple (""the yarn I tangle in my claws""), brown, blue, white (""the clouds floating in the sky""), or orange. ""Is it orange? Yes! . . . the color of my mother."" The art is childlike and comforting, with broad, visible strokes of the brush. Impish and informational.
