Custom Visual Changing Titles

How can I import a theme or create a custom visual that has the same font, size, and color I select from the JSON. If somebody could please comment below how to accomplish this similar to my legend I would be forever greatful. I have looked into the documentation and cannot for the life of my figure it out.
