Since the models are the only ones that can see who is in the room as a collective group I think they should be able to tell if the person they are talking to is a model. I would think that could be easily identified by the font color. I know that it would help the models out immensely to relate to one another if they could identify each other. They could possibly even bounce ideas off each other. 
Another font color?
Let's see there is gray, white, gold, blue, purple, green, and pink. Did I forget one?
The models have a forum to themselves where they can bounce ideas off each other. It is private so only models/studios have access to it.
