Which of the following is NOT a principle of visual display in retail?

In retail visual display, the principles of balance, contrast, and focus play crucial roles in attracting and maintaining customer attention. Balance involves arranging visual elements in a manner that feels stable and aesthetically pleasing, ensuring that no single part of the display overwhelms the others. Contrast helps to differentiate products and draw the eye to specific areas by using differing elements like colors, shapes, or sizes. Focus directs the viewer's attention to the most important aspects of a display, emphasizing key items or promotions.

Color blindness, on the other hand, is not a principle of visual display; instead, it refers to a condition where individuals perceive colors differently or cannot see certain colors at all. While understanding color blindness can be important for accessibility in design, it does not function as a guiding principle for creating effective visual displays in retail settings. The emphasis on principles assists in ensuring displays are compelling and functional for the widest audience, aligning with best practices in retail strategy.
