People have always painted their bodies. The reasons are many: religous, ceremonial, or simply for decoration. In Brazil , the Kayapo Indians paint each other's bodies using the blue-black juice of the genipap fruit. An unpainted body can mean that the person has no one who cares enough to do it. Other indians regard an unpainted person as naked. Sometimes body painting can be quite complicated because every colour and shape has a particular meaning. A popular design among the Thompson Indians in North America was to paint half the face red and the other half black. Red brought the warrior good luck, while black gave his enemy misfortune. In decoration for a religious occasion, the Australian Aborigines use traditional colours and patterns and these are applied by a special person. For instance , when mourning , the mourners are covered in white paint. Among the Nuba in the Sudan, body painting is art for art's sake: it has no religious meaning, it simply makes the body more beautiful. In fact, as a man gets older and less attractive , he replaces paint by clothing. Also a man suffering illness or injury will wear clothes until he recovers. Throughout the world , because people like to decorate themselves according to their own customs. In the Western world there is a multi-million pound cosmetics industry with vast amounts of money being spent on advertising campaigns to persuade men and women to buy cosmetics.
