They can be created in many ways, the simplest by enclosing an area with an outline. They can also be made by surrounding an area with other shapes or the placement of different textures next to each other — for instance, the shape of an island surrounded by water.
Because they are more complex than lines, shapes do much of the heavy lifting in arranging compositions. The abstract examples below give us an idea of how shapes are made.
Looking at it this way, we can view any work of art, whether two or three-dimensional, realistic, abstract or non-objective, in terms of shapes alone.
We visually determine positive shapes the figure and negative shapes the ground.
One way to understand this is to open your hand and spread your fingers apart. Your hand is the positive shape, and the space around it becomes the negative shape. You can also see this in the example above. The area around it is negative.

The same visual arrangement goes with the gray circle and the purple square. But identifying positive and negative shapes can get tricky in a more complex composition. For instance, the four blue rectangles on the left have edges that touch each other, thus creating a solid white shape in the center. Which would you say is the positive shape?

What about the red circles surrounding the gray star shape? Remember that a positive shape is one that is distinguished from the background. What about the dark figure standing in the doorway?
Here the dark shape becomes the positive one, surrounded by a white background. If the two curvy edges between the black and white regions are assigned inward then the central white region is seen as a vase shape in front of a black background.
ARTH Shapes and Figure/Ground Relationship
No faces are perceived in this case. On the other hand, if the edges are assigned outwards, then the two black profile faces are perceived on a white background and no vase shape is perceived.Figure-Ground Perception
The human visual system will then settle on either of the interpretations of the Rubin vase and alternate between them. Functional brain imaging shows that when people see the Rubin image as a face, there is activity in the temporal lobe, specifically in the face-selective region   Perceptual process[ edit ] How does the brain decide in a visual scene which item is the figure and which are part of the ground?
This perceptual decision can be based on many cues, all of which are of a probabilistic nature. For instance, size helps us distinguish between the figure and the ground, since smaller regions are often but not always figures. Object shape can help us distinguish figure from ground, because figures tend to be convex.
Movement also helps; the figure may be moving against a static environment. Color is also a cue, because the background tends to continue as one color behind potentially multiple foreground figures, whose colors may vary.
