Is there a simple way to change the theme or color of the nav bar between instances in San Diego?

[CatchTheFletch]

In Rome and before I would change the color of the nav bar to quickly differentiate between my instances. Is there a way to do this in San Diego? It's not as natural to look at the url to see if it is dev, test, or prod compared to seeing the nav bar be a different color or having a completely different theme for each instance.

Actually that didn't seem to work. Isn't banner color what I should be setting to change the color up top behind all, favorites, etc?

yes i just checked that was only for UI16 for next experience we can go to  Now Experience Framework > Theme Management > Themes.
but its not letting me configure because themes are in another application and that application is private

That makes it sounds like it isn't possible. I assumed this would be simple but if not I'll deal with it.

Yes the way we use to do in other versions is not possible anymore 
unless you turn this polaris property off.
btw i was goinf to tell you about enabling dark theme that way you can have atleast two different options LIGHT or DARK. sheryl defined the whole process below.

As an alternative, I started using a browser-based environment marker. I usually can't control our customer's color schemes, and I wanted a quick visual way to see no matter how many tabs I had open.

There is one built into snutils that will add a dot to every browser tab for that instance: https://www.youtube.com/watch?v=tm8-63yKmtY

I use Environment Marker for Firefox: https://addons.mozilla.org/en-US/firefox/addon/environment-marker/ You can choose the color, placement, and size of the banner as shown below.
