Footer background will not change color

I’ve been trying to change the color of my footer background, but It doesn’t seem to want to change for me. My site can be seen here

Below is the code that I used in my Child Theme’s style.css file:

footer#footer{
background-image:   url('https://www.feliciasantos.com/wp-content/uploads/2013/10/navigation-background.jpg');
background-repeat:  repeat;
background-color:   #6f963e;
}

Is there any other way that I could change the background color of my footer?
