Following the principle of design, what can be described as the visual empty spaces created between solid shapes in a showpiece?

The correct answer is negative spaces, which refers to the areas around and between the focal elements in a design. In the context of a showpiece, these visual empty spaces are integral to the overall aesthetic and balance of the composition. They help to define the shapes and forms present, allowing each element to stand out more distinctly. Negative spaces enhance visibility and can contribute to the rhythm and flow of the design, guiding the viewer's eye and creating a sense of harmony. This principle is essential in both art and design, emphasizing that empty areas can be just as important as the solid forms themselves. This understanding helps designers create more dynamic, engaging, and visually interesting pieces.
