Change contrast in open window selecting window

Holding down the [Alt] key and pressing the [Tab] key will open a small window containing icons of all of your open windows. Repeatedly pressing the [Tab] key cycles through the icons. Release both keys on your selection to pull it to the front.
I want to change the colors in this little window. Because the selection is not very visible, the contrast is not enough. How to change the contrast in this window?

There might be a more simplistic solution that involves some config file editing, but have you looked at any potential GNOME Extensions that might give some more customization potential? The one below seems like it might enable a different-enough visual look to suit what you’re looking for?
