Murals
A mural is any piece of artwork painted or applied directly on a wall, ceiling or other large permanent surface. A distinguishing characteristic of mural painting is that the architectural elements of the given space are harmoniously incorporated into the picture.



Trompe L'oeil
Trompe-l'oeil (French for "deceive the eye") is an art technique that uses realistic imagery to create the optical illusion that the depicted objects exist in three dimensions. Forced perspective is a comparable illusion in architecture.



Marbleizing
Marbleizing or faux marbling is the preparation and finishing of a surface to imitate the appearance of polished marble. It is typically used in buildings where the cost or weight of genuine marble would be prohibitive. Faux marbling is a special case of faux painting used to create the distinctive and varied patterns of marble - the most imitated stone by far.



Kids Room
This is a technique to paint kid's favorite 2D cartoon characters or scenery on the wall unlike realistic trompe l'oeil murals.



Faux
Faux painting or faux finishing are terms used to describe decorative paint finishes that replicate the appearance of materials such as marble, wood or stone. The term comes from the French word faux, meaning false, as these techniques started as a form of replicating materials such as marble and wood with paint, but has subsequently come to encompass many other decorative finishes for walls and furniture including simulating recognisable textures and surfaces.
