This vibrant, thoughtful book from Katz (Over the Moon, 1997) continues her tribute to her adopted daughter, Lena, born in Guatemala. Lena is “seven. I am the color of cinnamon. Mom says she could eat me up”; she learns during a painting lesson that to get the color brown, she will have to “mix red, yellow, black, and white paints.” They go for a walk to observe the many shades of brown: they see Sonia, who is the color of creamy peanut butter; Isabella, who is chocolate brown; Lucy, both peachy and tan; Jo-Jin, the color of honey; Kyle, “like leaves in fall”; Mr. Pellegrino, the color of pizza crust, golden brown. Lena realizes that every shade is beautiful, then mixes her paints accordingly for portraits of her friends—“The colors of us!” Bold illustrations celebrate diversity with a child’s open-hearted sensibility and a mother’s love.
