Little Blue and Little Yellow are best friends, but one day they can’t 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 with a message that will resonate with children today as strongly as it did then.
