What design element creates visual interest through repetition of colors and shapes?

The element that creates visual interest through the repetition of colors and shapes is pattern. Patterns are fundamental in design because they can generate rhythm and cohesion within a space. They often consist of a series of repeated motifs or designs, which can include geometric shapes, floral designs, or abstract forms. By using patterns strategically, interior designers can enhance the aesthetic appeal of a room, create focal points, and contribute to the overall ambiance.

Texture primarily refers to the surface quality of materials and how they feel, which adds depth and interest but does not inherently involve repetition of shapes or colors. Style encompasses the overall design theme or genre (like modern, traditional, etc.) rather than focusing specifically on the repetition of elements. Form deals with the three-dimensional characteristics of objects within a space and, while it is important in terms of how things fit together, it does not emphasize the repetition that patterns do. Thus, pattern is the correct choice as it directly relates to the visual interest achieved through repetition.
