João Paulo Seara Cardoso wrote A Cor Do Céu drawing inspiration from his childhood memories; he also included questions his daughter asked and episodes of Lewis Carrol’s Alice in Wonderland and Saint-Exupéry’s The Little Prince. Júlio Vanzeler created the puppets and designed the illustrations for the text published in 2004.

Two forms of theatre are presented on stage: the story of the two children is played by actors and that of the other characters is represented by puppets or by actors wearing costume puppets.

One morning, in a house with a garden, two children walk a robot-dog and ask each other questions about the world: how can we measure love? why does the sky change colours? when a flower is plucked, does it hurt?

The children keep asking questions, and try to answer some of them: is a storm just an angry cloud? can we find infinity where the sea ends?

This journey in the world of whys is completed by several stories in which eccentric characters like a balloon-hippopotamus, a widow-caterpillar, and a cow-fish mix with Humpty Dumpty, Hansel and Gretel, and the Little Prince. The children tell their stories while doing household chores. The widow-caterpillar saw her husband die, run over by a bike, but she remains cheerful. The balloon-hippopotamus has been floating in the sky since the previous summer, but only the little girl can see it. As for the cow-fish, it appeared the day several cows fell in the sea and transformed after eating seaweed. The last story of the day chosen by the children is the one about Bicho Papão (Bogeyman) because he is not so evil after all.
