Which design principle focuses on the arrangement's focal point?

The principle that focuses on the arrangement's focal point is emphasis. Emphasis in floral design refers to the area or object that draws the viewer's attention first within an arrangement. This principle ensures that there is a specific point of interest that stands out, allowing the design to communicate effectively and capture the observer's gaze.

When applied in floral design, emphasis can be achieved through various techniques, such as using contrasting colors, varied shapes, or larger flowers to highlight the focal area. This principle is crucial because it helps to establish a visual hierarchy, thereby guiding the audience through the arrangement in a meaningful way.

Though balance, harmony, and proportion are vital design principles that contribute to an aesthetically pleasing arrangement, they do not solely concentrate on creating a focal point within the design. Balance aims to distribute visual weight evenly; harmony refers to the cohesiveness and integration of elements, and proportion deals with the size relationship between different components in the arrangement. While these aspects are important for creating a successful floral design, emphasis specifically directs attention to the key focal point that is intended to stand out.
