Koodiyattam, a classical Sanskrit theatre form of Kerala, influenced the development of other theatre styles like Krishnattam and RamaAttam. These theatrical styles eventually led to the emergence of Kathakali as a classical dance form of Kerala. Kathakali is well-suited for open-air performances against Kerala's lush greenery, requiring no props as dancers use gestures and facial expressions to depict scenes. Color plays an important role in Kathakali, with different hues indicating character types - green for nobility and virtue, red for royalty combined with evil, and black for wicked females. Kathakali displays remarkable use of eye movements and expressions.
