Which design principle refers to harmony among all parts of the composition?

• A. Rhythm
• B. Unity
• C. Balance
• D. Contrast

Answer: (B)

Unity means harmony among all parts of the composition. When a design has unity, colors, typography, shapes, and spacing feel like they belong together, creating a single, cohesive whole. This coherence lets the viewer’s eye travel smoothly across the piece without being interrupted by mismatched elements, because a consistent grid, shared color palette, and repeated motifs tie everything together. Rhythm, Balance, and Contrast each describe important effects in design—rhythm is about movement through repetition, balance is about distributing visual weight, and contrast is about differences to emphasize some parts—but unity specifically captures the overall harmony that makes all components feel like one complete work.
