Storing the background color in a JavaScript variable

I've been experimenting with creating a fade in and out effect for a background image on a website. I've also been attempting to capture the background color of a div and store it in a variable. Here's what I have tried:

 elem = document.getElementById('nav');
 bgColor = elem.style.backgroundColor;

However, when I try to display the bgColor variable using alert(bgColor), all that appears is an empty text box. Despite researching various Stack Overflow questions and trying multiple solutions suggested, I haven't been successful in capturing the actual color in a variable.

Make sure to utilize window.getComputedStyle 
because otherwise, you will receive the "direct" styles that are lacking content.
