Here is a great script from the Stack exchange to allocate colors to each individual scene. Great for when you get lost mode switching and Blender forgets to change from the current scene.
Grab it at:
- Goto the scene properties > scene tab and set the color for the Info bar.
- create a new scene and repeat step 1
Each time you swap to another scene the Info bar changes color so that you can see it from the corner of your vision. Great for keyboard cruisers!
