Bernat is an angry chameleon. He doesn't like to change colour or for other chameleon to do so. He is always alone and likes his angry colour. One day he meets Serafí, another chameleon who makes him see that what Bernat thinks is an angry colour, is really the colour of sadness. Slowly Bernat begins to realise that to have friends and try the colours of all the different feelings and emotions life has to offer is much better than being alone, sad and angry.
