Change background color of navigation menu

I absolutely love Travelify and how easy you’ve made it to adjust the theme. Just one question: can I change the color of the background on the navigation menu? I change my header image monthly and would like to change the navigation menu colors to complement the major colors in my header images. Here’s the site if you want to have a look: http://www.phototrippingamerica.com

Thanks for all of your help!

I think I’ve figured it out myself. Sorry to have bothered you!
