[SOLVED] changes colors

How can I change the background of the menu located in the 'left-2' position? The background remains blue. I have already adjusted this in the layout module for 'left-2' (see attachment 1). As a test, I changed the corner settings, and those did update (see attachment 2).
Is it possible to change everything that is currently blue to a custom color of my choice (I would like to use #7A2E1E)?

Thank you. 
I suspect that you have set the 'bg-primary' color (defined as blue) within the section or a module position located inside it, and that this color is taking precedence. Please check this, and if you find such an entry, remove it. Once removed, the colors should be applied correctly. Go to the section's layout settings and check the 'Custom Class' field; that is where the entry will be. Delete bg-primary.

 

 

Thank you. There is one more setting I cannot seem to find: the line that appears beneath the menu items in the main menu. It is currently blue, but it should also be brown. This line only becomes visible when a menu drops down.
Kind Regards

This line is linked to the 'Primary' color. You can either change the 'Primary' color or use the following CSS code:

.megamenu-container, .megamenu-container .nav-submenu .nav-submenu { border-top: 4px solid #7a2e1e; }

The CSS code must then be inserted into the custom CSS section within the template options.
