Materials, patinas, decorative coatings, embossed coatings, aged waxed plaster

This is a classic and revealing exercise of a "hand" for a decorative painter. To know how to reproduce a material like this fake marble without the result attracting the eye, but everything seems normal without being able to discern the true from the fake... The reward is not to realize this when you enter the room. The opposite would be a lack of taste and a poorly done job.
