Change background color of Celonis Frontend to identify Development vs. Quality vs. Production

Hello Celonis community,
is there an option to change the background colour of the Celonis frontend (onPrem Version)?

As we are using a three system landscape (D, Q, P) it would be helpful to immediately recognize in which system I am currently locked in e.g. redish background for development system, yellowish background for testing/quality system.

Thanks and best regards,
Michael
