One winter morning, Otto the cat looks out the window and sighs, "Why is everything so grey today?" Luckily, his friend Leon the chameleon is around to show him just how many colours there are in the world. In these exciting and funny spreads, Leon and Otto identify people, places, and things of every hue. On pages dedicated to a single colour, Tom Schamp's drawings play with perspective and unexpected pairings. An enormous Bengal tiger lords over an orange-tinted world, while a giant blue whale dwarfs elephants, pairs of jeans, and police officers. Throughout, puns and allusions elicit laughs from parents and children alike.
