The polar bear is bored of his white environment and his hard life. He dreams of soaking himself in all the luminous colours of the rainbow. But when his wish is granted, he realises to his cost that his arctic camouflage no longer works and he needs the advice of others to escape his prism...

A moving tale of hopes and dreams from an award-winning picture book team. The lyrical text is complemented by beautiful watercolours in which the joy and pain of the Rainbow Bear sing out.
