Add something to help identify internal messages sent by core.

Is your feature request related to a problem? Please describe.

When sending messages to crew members, it is hard to differentiate between messages sent by core and messages sent by crew members.

Describe the solution you'd like

I believe that changing the color of the username for messages sent by core on the core side would be helpful to identify who is talking.
We could do something similar on the crew side, but that would be less important, as the messages already show up with a buffer to left or right.
