What are the primary colors of electrical safety warning signs?

The primary colors of electrical safety warning signs are indeed red, yellow, and orange. This color scheme is designed for clear communication of hazards and safety information.

Red is universally recognized for indicating immediate dangers or prohibitions, often used for signaling a stop or to indicate equipment that should not be used without caution. Yellow is used for warning signs that indicate caution is needed, alerting individuals to potential hazards that could cause injury.
