Answer:

Buon fresco is an Italian expression to describe a wall painting that is made on the last wet layer of lime and sand mortar, called plaster, so that the pigments, mixed with water, are fixed by the carbonation of lime. In this type of frescoes, the pigments are alkaline resistant, that is, they are resistant to color degradation.
