Which element of design would best support achieving balance in artwork?

Achieving balance in artwork is primarily related to the distribution of shapes within the composition. Shapes contribute significantly to visual weight and spatial arrangement, which are crucial for creating a sense of equilibrium in a piece of art. When shapes are distributed thoughtfully across the canvas, they can attract the viewer's eye evenly or create a counterbalance that makes the artwork feel harmonious.

For example, a large, dark shape on one side can be balanced by several smaller, lighter shapes on the opposite side. This interplay creates a visual relationship that gives the artwork a stable feel. In contrast, focusing solely on elements like texture, color choices, or size variations, while important in their own rights, do not directly address the foundational aspect of balance as effectively as shape distribution does. Through the careful arrangement of shapes, artists can manipulate the overall composition to evoke certain emotions or direct the viewer's gaze, reinforcing the importance of this specific element in achieving balance.
