David Attenborough explores the vital role that colour plays in the daily life of various species. For us humans, it is a source of aesthetic beauty and expression, but for animals it is an essential tool used for survival and without it, there would be catastrophic consequences. Colours help animals to win a mate, to fight off rivals and to warn enemies. Attenborough explores nature's use of colour using technological advancements in camera equipment to reveal the world, as seen by animals.
