What color signifies emergency communication in the cabin on the Attendant Indication Panel (AIP)?

Emergency communication within the cabin is signified by the color red on the Attendant Indication Panel (AIP). This color is universally recognized for indicating critical situations that require immediate attention, ensuring that cabin crew can quickly distinguish between different types of messages. The use of red in emergency protocols is consistent across various aircraft and safety systems, reinforcing the urgency associated with emergencies. Other colors on the panel typically represent non-emergency communications or normal operations and thus do not convey the same level of immediacy. Therefore, red serves as a vital and immediate alert mechanism for flight attendants, guiding them in their response to various situations within the cabin.
