Which colors represent transmit (TX) and receive (RX) on the SNAP?

The colors associated with transmit (TX) and receive (RX) on the SNAP are standardized for consistency and clarity in communication protocols. In this case, blue represents RX (receive) and red represents TX (transmit). This color-coding helps operators quickly identify the direction of data flow in communication systems.

When correctly using the color codes, it allows for efficient troubleshooting and system monitoring, as operators can easily distinguish between outgoing and incoming signals. Understanding these fundamental color associations is crucial for maintaining effective communication and operational integrity in a digital communication environment.

The other options do not align with the established standards for signaling in this context, providing incorrect or swapped associations for the TX and RX indicators.
