Ultra boxed layout – how to change colors

A developer transferred the site to our host’s server and it’s pretty much what we wanted. The dashboard at wp-admin offers most of the tools we need to tweak things. But we have failed to find where the menu option is to adjust the background color INSIDE the boxed area in Ultra theme’s boxed layout.
All of the guidance we have found online directs us to menu items (like “theme panel”) at the left in the dashboard that we don’t see in our version. Are we missing something, or is it possible that the developer has limited our permissions (roles and capabilities) to change some features?
Thanks!
