How can I change only the drop-down menu color?

[Benbox1]

Hi all is there a way to change only the drop-down color of the menu selector and dropdown menu color but nothing else on the page including not changing the secondary background color. 

Cheers for any assistance.

Please add the following code at the bottom of your assets/theme.css file.

.mega-menu {background: #c9e2f7 !important;}

Thanks!
