Answer:
A Variety
Step-by-step explanation:
The principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety. The use of these principles can help determine whether a painting is successful, and whether or not the painting is finished.
Variety, because there are no different elements used, like lines, shapes, and colors, they are not placed against each other. that's what makes up the variety of a painting.
