Daywalt and Jeffers' wandering crayons explore love. Each double-page spread offers readers a vision of one of the anthropomorphic crayons on the left along with the statement "Love is [color]." The word love is represented by a small heart in the appropriate color. Opposite, childlike crayon drawings explain how that color represents love. So, readers learn, "love is green. / Because love is helpful." The accompanying crayon drawing depicts two alligators, one holding a recycling bin and the other tossing a plastic cup into it, offering readers two ways of understanding green. Some statements are thought-provoking: "Love is white. / Because sometimes love is hard to see," reaches beyond the immediate image of a cat's yellow eyes, pink nose, and black mouth and whiskers, its white face and body indistinguishable from the paper it's drawn on, to prompt real questions. "Love is brown. / Because sometimes love stinks," on the other hand, depicted by a brown bear standing next to a brown, squiggly turd, may provoke giggles but is fundamentally a cheap laugh. Some of the color assignments have a distinctly arbitrary feel: Why is purple associated with the imagination and pink with silliness? Fans of The Day the Crayons Quit (2013) hoping for more clever, metaliterary fun will be disappointed by this rather syrupy read. As ephemeral as a valentine.
