Which component is most associated with visual harmony in design?

Balance is most associated with visual harmony in design because it refers to the distribution of visual weight within a composition. A well-balanced design creates a sense of stability and coherence, allowing viewers to engage with the content seamlessly. When elements are arranged in a balanced manner, whether symmetrically or asymmetrically, it fosters a sense of order and unity, making the overall visual experience more harmonious.

In contrast, while contrast is important for differentiation and can highlight specific elements, it may contribute to an imbalance if not used carefully. Style encompasses the aesthetic choices and visual language of a design but does not inherently address the distribution of visual elements. Proportion deals with the relationships between the sizes of different elements, which can influence harmony but is not the primary component focused on overall balance and visual weight. Thus, balance is key to achieving visual harmony in design.
