Color of SAP GUI windows

I’m posting a small hint which helps to recognize in which SAP system you are connected via SAP GUI. Sometimes when you are working with several sessions in different systems and you switching between windows very often it is problem to do not get confused.

To avoid such an mistakes you can change the color of SAP GUI windows for production client screen to red color for test systems to some different color and as well some other color for development systems. Procedure to do so is following:

Log in to some SAP system in which you want to change the color via SAP GUI -> select Customizing local layout (ALT+F12) -> Set color to system (select color) -> Save.
