How to stop VSCode having colored tab names

Question

Since some recent update, VSCode started adding colors to tab names as seen here:

The blue, orange. No idea what the colors mean.

But I want to turn it off and have all tabs be black if it's possible.

Answer 1

I assume you are using the Insiders' Build. You can disable those tab "decorations" with these settings:

Workbench > Editor > Decorations: Colors
Workbench > Editor > Decorations: Badges

Those would override your tab foreground if you don't disable them.

Then you color your tab colors if you need to.

Answer 2

Go to settings.json and paste

 "tab.inactiveForeground": "#000000",
 "tab.activeForeground": "#000000",

The first one is for the color of the inactive tab name and the second one is for the color of the active tab name.

P.S. don't forget to put it inside

  "workbench.colorCustomizations": {
     "tab.inactiveForeground": "#yourcolor",
     "tab.activeForeground": "#yourcolor",
}
