What do you call a picture painted on a wall or ceiling before the plaster is dry?
A picture painted on a wall or ceiling before the plaster is dry is called a "fresco." This technique involves applying water-based pigments onto freshly laid wet plaster, allowing the paint to bond with the wall as it dries. Frescoes are known for their durability and vibrant colors, as they become an integral part of the wall surface.
