I would like to change the background color for my site, but I don’t have an image per se. Is there a way to just choose a color without having to change the custom css or theme files? Or do I need to upload a background image of a color (which works - I’ve tried, but is a strange strategy). Any suggestions would be helpful! Thanks.
