You can change the color of the background as well as the “Your logo here” image. It is just the external image URL added to the field by default. After you drag and drop the header field, you can edit the header field by clicking on the edit button in the left end of the field. Also, in the right end, you have provided with the option to delete the template field you created. These options will surely help you create the template in your own way desired way. Please take a look at it and sort out your problem.
