Ancient temples and palaces in Kerala, India, display an abounding tradition of mural paintings mostly dating back between the 9th to 12th centuries CE when this form of art enjoyed royal patronage.
Although the traditional mural artisans were under the patronage of various rulers in Kerala, under British administration the art form suffered enormously, even at the danger of extinction.
The Centre for Study of Mural Paintings, a school established by Guruvayur Dewaswom Board in the Thrissur district of Kerala under the chief instructorship of Mammiyoor Krishnan Kutty Nair, represents this revival phase,[1] as does the Sree Sankaracharya University of Sanskrit in Kalady under the instructorship of Dr.Saju Thuruthil.
Leaves of Neelamari (Indian Indigo; Indigofera tinctoria ) plant are squeezed and the extract is used after drying up to be mixed with Eravikkara (Garcinia morella) for obtaining the green pigment.
Wooden utensils are used for mixing the colours and the binding media used is derived from tender coconut water and extracts from the Neem tree (Azadirachta indica).
