File header's background color should be in such a way that we can clearly figure out which file we are in

Describe the solution you'd like
So as of now if we have some files opened, due to color combination its a bit hard to figure out which file is currently opened. We should change the file header's background color to make that clear.

in the attached image, we can not clearly differentiate between which file is actually opened.

I've added the following to my VSCode user settings:

  "workbench.colorCustomizations": {
    "[Night Owl Light]": {
      "tab.activeBorder": "#994cc3"
    }
  }

This add a border to the bottom of the active tab:

thanks @m-allanson
I was actually getting around by that by just setting the background color.
