Which of the following is considered NOT a basic principle of visual design?

The principle that stands out as not belonging to the fundamental concepts of visual design is the idea of showing what you are saying verbatim. This principle focuses on transcribing speech or text directly rather than emphasizing how visual design can enhance communication and engagement.

In effective visual design, the goal is to complement and reinforce verbal messages rather than duplicate them. This is achieved through various techniques such as contrast, which helps differentiate elements on a visual display; consistent color schemes that create a cohesive look and feel; and effective use of imagery that captures attention and conveys concepts dynamically. None of these involve verbatim text, which can often lead to redundancy and disengagement for an audience. The emphasis in visual design is on clarity, aesthetics, and supporting the message visually, rather than repeating it in written form.
