Vibrant colors and striking contrasts characterize an engaging concept book that invites child participation. “Lemons are not red,” reads the text on the opening page spread, which is washed in bright yellow brushstrokes. The visual focus of the page spread is the die-cut shape of a lemon on the right hand side. The color of the page beneath the die-cut is red, underscoring the text. Turn the die-cut page and the text reads, “Lemons are yellow, apples are red.” The lemon now appears yellow on the left, and a round red apple is the focus on the right. Each pair of page spreads works in the same way, pairing two colors and two objects that suggest some sort of relationship (flamingo and elephant, carrot and eggplant, grass and sky, reindeer and snowman, moon and night). Laura Vacarro Seeger’s deceptively simple book is a masterful blend of idea, design and execution. (Ages 2–6)
