Final answer:
The statement that signs must use a negative suggestion is false. Signage can use both positive and negative language, and the effectiveness of a sign also depends on whether its design and material match the nature of the business.
Step-by-step explanation:
The assertion that wording on signs must use a negative, rather than a positive suggestion is false. Signage can utilize both positive and negative language depending on the message it intends to convey. Additionally, the appropriateness and effectiveness of signage also depend on the congruency between the sign's design, materials, and the services or products being offered. For instance, while wooden signs may complement rustic businesses such as a Bar-B-Q restaurant or a cowboy boot store, they might not be suitable for technology-oriented businesses like a laptop or higher-definition television retailer.
To illustrate, a sign conveying a prohibition or warning may employ a negative suggestion, such as "No Smoking" or "Do Not Enter." Conversely, signs intended to guide or invite, like "Welcome" or "Please Enter," use a positive tone. Importantly, businesses should align their sign's material and style with their brand image to avoid creating misleading impressions.
