Definition
Fresco is a painting technique where pigments are applied to freshly laid, or 'wet,' lime plaster. The pigments bind with the plaster as it dries, creating a very durable and long-lasting artwork. Think of it as painting directly onto a wall that becomes part of the artwork. It requires careful planning and quick execution, as the artist must work while the plaster is still wet. Frescoes are often used for murals and large-scale decorative works. The technique was popular during the Renaissance and is known for its vibrant colors and permanence.
