How to chang background color of the section below tab bar?

I want to change background color of the section which below the tab bar but I don’t know what name is it.

Thanks!

I tried with some option in tab bar but it not work.

>Solution :

That is controlled by the breadcrumb properties found in workbench.colorCustomizations:

"workbench.colorCustomizations": {
    "breadcrumb.background": "#ff0000",
    "breadcrumb.foreground": "#00ff26"
  }
