Hi, I've an amateur slowly learning how to modify the backend of websites. I"ve been able to figure out most small things.

But I've struggled to find a way to change the header on a template I started using for a personal blog (blog.joekoss.m e). I'd like to start by just being able to change the color. It'd be nice to have the option to change the header to a .jpg as well. I figure there is an easy way to do it. I am either overlooking...
