What is the main purpose of a color palette?

The main purpose of a color palette is to create visual harmony using a consistent selection of colors. A well-chosen color palette helps unify the various elements of a design, ensuring they work together cohesively. This consistency can evoke certain emotions, highlight important features, and enhance the overall aesthetic appeal of the design.

Using a coherent color palette allows designers to communicate their message effectively, drawing the viewer's attention to key areas without the distraction of clashing colors. By selecting a specific range of colors, designers can establish a recognizable brand identity or thematic continuity in their work.

The other options focus on different aspects of design that are not directly related to the function of a color palette. While affordability, size of graphic elements, and typography are crucial components of the overall design process, they do not pertain to the primary role of establishing a harmonious color scheme.
