Hi,
You can go to Appearance > Widgets > drag & drop widget "Soledad List Banners" to "Main Sidebar" and config it.
To change color of the text & background on this widget, please try add more this code to Customize > Custom CSS:
.penci-promo-text h4{ color: #ffffff; background: #ff0000; }
You can change color codes ffffff and ff0000 on above code to any color code as you want. You can get a color code here
Best Regards,
