Nirmal paintings depict a wide range of expressions through subtle use of numerous colors. The expressions in these paintings appear real and sparkling. Nirmal is actually a place in Adilabad district and these paintings were named after the place of their origin. Initially, this work of art was exclusively practiced by a group of artisans known as 'Nagash'. In the 14th century, the 'Mughal' rulers patronized this art since they were mesmerized with its charm. Nirmal paintings are based on various themes, suggesting sharp influence from Indian schools including Kangra, Ajanta and Moghul miniatures.
The Nirmal art is generally found in the Nirmal town, Adilabad district of Andhra Pradesh. Here, many craftsmen known as Nakash reside. They are involved in Niramal arts, in which scenes from the Hindu epics, Mahabharata and Ramayana are painted. These craftsmen use indigenous colors made from minerals, gum and herbs.
