What is the medium used in fresco painting?

Fresco painting is characterized by the use of wet plaster and pigments. This technique involves applying pigments mixed with water onto freshly laid wet plaster. As the plaster dries, the colors become an integral part of the wall surface, allowing for vibrant and long-lasting artwork.

The use of wet plaster is crucial because it allows the pigments to bond with the wall, making the artwork durable and resistant to the elements over time. Different types of fresco techniques, such as buon fresco (true fresco) and secco fresco, rely on this foundational practice, further emphasizing the importance of the medium.

The other options represent different artistic mediums that do not align with the historical practice of fresco painting. Canvas and oil are typical in oil painting, while wood panels and tempera refer to different traditional techniques. Digital screens pertain to modern digital art forms, which are not relevant to the ancient practice of fresco painting.
