Design Principles

The principle of similarity, a Gestalt perception principle, states that similar elements are perceived as a single group, enhancing their relatedness. For example, a matrix of dots and squares is interpreted as rows due to the visual similarity. This grouping reduces complexity, while dissimilar elements are viewed as separate. Color similarity is the most effective, followed by size and then shape. Designers should use similarity to convey relationships, keeping colors and shapes simple for stronger grouping effects.
