my mail.app suddenly stopped showing me to/cc header detail in all emails. I had a better look at it and those headers are there, but are displayed in white color. Details on image:
I tried changing color via Command + T, but it seems that it only changes email color, not text color. I also tried to remove file from ~/Library/Preferences/com.apple.mail.plist and restarting the Mail.app, but that didn't help either.
How should I restore to the default behaviour?

In case the system fonts got modified somehow I recommend to reset them.
To do this open the app called Font-book and under the File tab click on the "Restore standard Fonts". Then, reboot the computer.
That should fix your problem.
