upper triangle depicts the trunk and the lower triangle the pelvis. Their precarious equilibrium symbolizes the balance of the universe, and of the couple, and has the practical and amusing advantage of animating the bodies. The pared down pictorial language is matched by a rudimentary technique. The ritual paintings are usually done inside the huts. The walls are made of a mixture of branches, earth and cow dung, making a Red Ochre background for the wall paintings. The Warli use only white for their paintings. Their white pigment is a mixture of rice paste and water with gum as a binding. They use a bamboo stick chewed at the end to make it as supple as a paintbrush. The wall paintings are done only for special occasions such as weddings or harvests. The lack of regular artistic activity explains the very crude style of their paintings, which were the preserve of the womenfolk until the late 1970s. But in the 1970s this ritual art took a radical turn, when Jivya Soma Mashe and his son Balu Mashe started to paint, not for any special ritual, but because of his artistic pursuits. Warli painting also featured in Coca-Cola's 'Come home on Diwali' ad campaign in 2010 was a tribute to the spirit of India's youth and a recognition of the distinct lifestyle of the Warli tribe of Western India. Tribal Cultural Intellectual Property Warli Painting is the cultural intellectual property of the tribal community. Today, there is an urgent need for preserving this traditional knowledge in tribal communities across the globe. Understanding the need for intellectual property rights, the tribal non-profit Organisation "Adivasi Yuva Seva Sangh" initiated efforts to start a registration process in 2011. Now, Warli Painting is registered with a Geographical Indication under the intellectual property rights act. With the use of technology and the concept of social entrepreneurship, Tribals established the Warli Art Foundation, a non-profit company dedicated to Warli art and related activities. Culture The Warli were traditionally semi-nomadic. They lived together in small-scale groups with a headman leading them. However, recent demographic changes have transformed the Warli today into mainly agriculturists. They cultivate many crops like rice and wheat. Warli women wear toe-rings and necklaces as a sign of being married. Some Warli practice polygyny.
