Differentiate Adobe Campaign Production and Dev instances

It is difficult to use Adobe Campaign Classic if you are a multi tasking person when you have opened Development instance and Production instance at same time. You have the same set up available in both instance. When you want to update something in development instance and unknowingly you're updating in production instance, it will be definitely difficult to use two instance at same time.

So we might have any colour differences in the icon or console window screen to differentiate between Production and Development instance.
