Customize theme by Tenant

We have Non-Prod and Prod Tenants in our Automation Cloud. There have been times when someone made a change in one tenant while in the incorrect tenant.

If we can customize the color theme by tenant, I can have one tenant with dark theme and one with light to quickly tell which I’m working in (I know that you can change the color of the line at the top by Tenant, but this doesn’t really jump out at me).
