Hello Frank,

Footer we can apply whatever color is provided to us.

To focus heading or any other content on different pages you guys need to apply tabindex=0 inside HTML elements. This is not a coding job it is something to be editable using the WordPress page editor. Please check the screenshot. 
If still, you guys can not manage let us know what we need to do on our end however this is not a coding job. If we will use code then it will be applied on all heading in the websites.
