Skinning the Content Manager Explorer
To make a clear, visible distinction between the different environments, you can skin the user interface.
About this task
When implementing SDL Tridion Sites, to manage the development process and clearly separate the project implementation phases it is recommended to use a Development, Test, Acceptance and Production infrastructure (DTAP). DTAP enables different users to manage different types of content on different Content Manager servers: the creation and management of content is distributed over several machines to prevent different types of content from getting in each other's way. You then use Content Porter to port data from one SDL Tridion Sites environment to another.
