Kathakali is one of the oldest theatre forms in the world. It originated in the area of southwestern India now known as the state of Kerala. Kathakali is a group presentation, in which dancers take various roles in performances traditionally based on themes from Hindu mythology, especially the two epics, the Ramayana and the Mahabharata.
The most interesting aspects of Kathakali is its elaborate make-up code. Characters are categorized according to their nature. This determines the colours used in the make-up.
