What color signifies a collision alarm?

The color yellow is typically used to signify a collision alarm. This is because yellow serves as a cautionary color, alerting individuals to pay attention to their surroundings and potential hazards without implying an immediate danger. In the context of safety protocols and alarms, yellow captures the need for vigilance and readiness to act, while not inciting panic.

The other colors serve different purposes in various contexts; for instance, red often indicates immediate danger or emergency situations, like fire alarms, that require action to avoid harm. Green is generally associated with safety and all-clear signals, indicating that everything is secure. Orange typically denotes a warning, but it is less standardized than yellow when specifically referring to collision alarms.
