Here’s how to do it.
Then go to System > Preferences > Gnome Color Chooser to launch the program.
you could change font, font color, background and background color of the panels and start menus.
Tick the “Normal” option and choose the color you want for the panel font.
The first two options are pretty straight forward, they change the typeface and the size.
it’s possible for you to customize them just the way you did with the panel.
Alright, this was the easy way to change the font of your panels.
If there are any other lines in the file leave them intact.
When done close and save the file.
Don’t change any other thing in the text.
When done, save and close.
