Change the Header Formatting?

^^That’s a screenshot of the header as-is. The client is poor and cannot afford a custom header so we’re using the “Type it here and save it” header. :)

Except, I can’t find a way of editing any of the formatting. I’d like to make AF Christian Fellowship larger and a different color but although I can find the place to edit the padding and the font type, I can’t find size or color. I imagine most people don’t use this header which is why you haven’t put the controls into the dashboard; if you give me the custom CSS with the default size and color in it, I can put that into the custom CSS section and edit from there.

Thank you!
