What style of Roman wall painting use flat colors in marble like finishes

Answer 1

The style of Roman wall painting you are referring to is known as the Second Style (also called "Architectural Style" or "Illusionistic Style"). This style, which emerged during the late 2nd century BCE, is characterized by a more naturalistic approach and often features flat colors that mimic marble or other materials, creating an illusion of depth and architectural elements. Artists would use painted columns, architectural features, and vistas that extended beyond the wall, effectively transforming the room into an imagined space of grand architecture or landscapes. This technique was used to enhance the richness of interior spaces in Roman homes and public buildings.
