They use very dark color paints which are handmade paints and it takes lots of efforts to do. There are some different kinds of Madhubani paintings called Has, Varani, Tantari, Godana, Kovar etc. So they use mainly bamboo sticks and match sticks to fill the colors. And it's very interesting our phone and I love it to do. Thank you all
This was actually very insightful and thank you for this. I am very interested in Madhubani arts. Thank you so much
