The general shipboard announcement system, known as 1MC, is represented by the color red. This color is significant as it indicates urgent announcements or important communications that require immediate attention from personnel on board. The use of red aligns with maritime communication protocols, where the color red often signifies warnings or critical alerts, ensuring that crew members recognize the urgency of the messages being conveyed.
