Hello @mandiedillard
Thank you for using Texton pro. We have added overlay in image so that title can be readable. If you want to adjust the overlay transparency then add the following code in dashboard-> appearance -> customize -> additional css.
.inner-header-image .overlay { background: rgba( 0,0,0,0.2); } // note: you can change the last value from 0.1 to 0.9 as per your requirements.
Regards
