Is it possible to open 2 Visual Studio Code sessions with different themes? Maybe like this:
Check out the Window Colors extension which:
Automatically adds a unique color to each window's activityBar and titleBar.
Maybe : Peacock
Subtly change the color of your Visual Studio Code workspace. Ideal when you have multiple VS Code instances, use VS Live Share, or use VS Code's Remote features, and you want to quickly identify your editor.

You can have a different theme per workspace/folder by adjusting the workbench.colorTheme in the workspace settings.
Now, whenever you reopen that folder, the color theme will match what you set in the workspace settings.
