Does anyone know how to remove the Title completely from Search Banner?

We have decided to use the Hero Image Itself as the title on the homepage.  When I try and delete the Title completely when editing, it keeps defaulting back to a title I had put in when I had set up a trial account.  So for now I just input a period but it still looks funky. 

If I can’t leave the title area blank would someone be able to direct me to the edit area in the platform where I can change the color of the title so it will at least appear invisible?  Thank you!
