What color is the light on the FA indicator for a standard call compared to an emergency call?

The light on the FA (Flight Attendant) indicator is colored green for a standard call and red for an emergency call. This color coding is designed to provide immediate visual cues to the flight attendants, indicating the urgency of the call being made by passengers. A green light signifies that the situation is standard, requiring attention but not immediate action, while a red light represents an emergency, alerting the crew to a situation that requires immediate response. This clear differentiation helps ensure that flight attendants can prioritize their actions effectively based on the nature of the call.
