We would like to be able to “brand” Litium Backoffice so that it becomes clear to an end user what environment they are logged in to, for example by having different backgrounds, color schemes or set an environment text somewhere. Is this possible somehow?
Litium version: 7
Easiest would be to look at the url of course 
Maybe there are some browser extentions there you can change page colors based on the url?
Maybe this:
This is not really a solution. It requires all end-users to install a plugin in a specific browser (Chrome).
What I am asking is whether we can configure Litium Backoffice somehow with different color schemes, different backgrounds or some way to get the environment name into the Backoffice GUI so that an end user can see that they are in the Production environment and not the QA environment and so on.
I am not looking for any client based workaround such as plugins etc.
Yes I understood that ofc, but how are you going to change code inside the DLL, there is no access to the source code.
