What is the typical background color for warning and caution signs?

The typical background color for warning and caution signs is yellow. This color is universally recognized for indicating potential hazards and cautionary situations, allowing for quick recognition by individuals. Yellow grabs attention due to its brightness and is commonly used in various applications, including traffic signage, construction sites, and safety warnings. The use of yellow for these signs is consistent with safety standards and regulations, ensuring that people are adequately alerted to potential dangers in their surroundings.

In contrast, green usually signifies safety or go, blue typically indicates informational signs or traffic messages, and purple is not commonly associated with warning signs, making yellow the clear choice for caution and warnings.
