Header Text Color Help

[kove_aiden]

I am using the "Ghouls Black" Expressive layout. I have already changed the header background image and the color of the strip behind the text. Now I would like very much to change the color of the text to red, so it will show up better. I have been experimenting (the way I figured out the other two modifications) but have been unable to change it. Any help would be great. Thanks.
