Little Blue and Little YellowBy: Leo Lionni Little Blue and Little Yellow are best friends, but one day they cant find each other. When they finally do, they give each other such a big hug that they turn green! With very few words and the power of a few scraps of coloured paper, this is a story of acceptance and friendship and a fantastic first introduction to colour blending abstract art. A true classic from four time Caldecott Honor winner Leo Lionni first published in 1959
