Caution signs must predominantly feature which color according to specifications?

Caution signs are designed to alert individuals to potential hazards or situations that require attention, and they predominantly feature the color yellow. Yellow is commonly associated with caution and warning in various contexts, as it is a highly visible color that captures attention quickly. This visibility is crucial for safety, allowing individuals to recognize a warning sign from a distance and respond accordingly to avoid potential risks.

In many standards and regulations surrounding signage and safety protocols, yellow is intrinsically linked to warning signs that indicate caution. This is why the utilization of yellow in caution signage is not only a practical choice but also a recognized standard across various industries and environments.

Other colors such as red, green, and blue serve different purposes in signage. For example, red is often used to indicate danger or prohibitive actions, while green is associated with safety or go-ahead signals. Blue, on the other hand, is typically utilized for informational signs rather than warning or caution. Hence, the choice of yellow for caution signs is both logical and important for ensuring safety and clear communication.
