Title bar should be colored to appear different from guest windows

[ChrisSca]

I suggest to color the host title bar in order to not confuse it with the guest windows.

Personally, I frequently click by mistake on the Close button of the host window, thinking I am closing a window in the guest area. It would greatly help if the host title bar, including buttons, had a different color.

I even suggest to let the user select a picture as the title bar background. That would avoid confusions even more since the picture is customized.
[ It may be something similar to the ​FireFox themes, or limited to the title bar itself. ]

Thank you

The host doesn't know how the guest looks. Your request is not feasible. You can customize your host or your guest appearance, so you don't get confused.

We don't apply fixed colors to the widgets. even if we do how can we make sure that host and guest look different. In any meaningful WM/DE you are able to apply colors/themes so that they look how ever you want them to.
