Hi @whereisaaron 

Thanks for reaching out to TP-Link Business Forums.

There is no unified standard for colour-coding. The different colours of AB are simply a quick way to distinguish between the A and B modules of the same model. The colour-coding between different models are not strongly related. 

If you think it necessary, you can post a vote in our Forums. If your thread gets more support, then it may be adopted in the future.

Thanks for your understanding and cooperation.
