This picture is an example of an in-store display from Target. There are many principals of design at work in this display including balance, repetition, rhythm, unity and harmony. Balance is seen through the use of side by side combinations, as well as mix and match pieces paired next to one another. Repetition of colors causes the eye to transition seamlessly across the display allowing for cohesion of the products. By setting all tops on the upper half of the display, grouping all bottoms underneath the display, it has a rhythmic quality. Because this visual display allows the customer to thoroughly understand and maneuver the product line well, with color cohesion, and display understanding, it overall has unity which works very well.
