What color indicates that you are currently speaking on the hi site radio?

The color red is used to indicate that a person is currently speaking on the hi site radio. This color association is standard in many communication systems, signaling to other operators that the channel is in use and that they should not attempt to interrupt or speak over the current speaker. Utilizing specific colors for different functions in a communication system helps ensure clarity and prevents overlapping transmissions, which can lead to misunderstandings or important information being missed.

Other colors, like green, yellow, or black, do not convey the same meaning within this context and are typically associated with different statuses or functions in radio communication systems. This highlights the importance of recognizing color coding in maintaining effective communication protocols.
