If you comment the line 80 of the file joomlaplates.css you will see the color of the menu.

I had the same problem and I solved it.

Inside the file css/joomlaplates.css find .uk-navbar and then put /* at the beginning and put */ at the ending.

You can see in this example.
.uk-navbar {
/* background: none!important;*/
}

Problem solved.
