Can you imagine living in a city where everything is gray? That’s what the city is like in which the painter Zinnober lives. But he loves colors! He has to hide his longing, because people in the city have grown accustomed to gray, until he meets the children Jonas and Paula. They are full of enthusiasm for blue, red, green, purple, yellow, orange—in all shades! Then something unheard-of takes place! Using old and new media, the piece after the children’s book classic “Zinnober in der grauen Stadt” (1973) by Margret Rettich shows how the joy of painting can become a source of creative thought in an urban environment.
