What does alternation in design refer to?

Alternation in design specifically refers to the use of two or more components in a sequence to create a rhythmic pattern. This technique is often utilized in visual arts and design to foster a sense of movement and flow within the composition. By repeating elements in an alternating fashion, designers can establish unity while simultaneously captivating the viewer through the inherent rhythm created by the pattern. This approach enhances the overall aesthetic of the design, making it engaging and dynamic.

The other options touch on different aspects of design principles, such as emphasis, proportion, and visual variety, but they do not specifically capture the essence of alternation. Emphasis focuses on making a particular element stand out, while proportion deals with the relationships between sizes of elements. Visual variety relates to using diverse elements to keep a design interesting. Each of these has its own role in design, but they are not directly synonymous with the concept of alternation.
