Totally white text on the panel bar in the GNOME

Before I did a fresh reinstall I had a custom shell theme that just modified the top panel colors to white. Now I can’t see it anymore because I was in a hurry and haven’t saved the latest scheduled /home directory (yes, I am relatively newbie to GNU/Linux).

So when I restored everything I forgot grey color of the text is not commenting I like to see like to see.
Maybe you’ll provide methods to make a scheleton or a just simple gnome-shell extension.
Thank you.
