Currently there are no options for changing the color for the header and for the footer, but this can easily be achieved using Custom CSS.

1. Log in to your WP Admin Dashboard
2. Go to Jobster > Layout Settings > Custom CSS

Header Color

#header {
    background: #000000; 
}
#header .middle-header-bg .middle-header {
    border-bottom: 0;
}

Footer Color

#footer {
    background: #000000;
}

Where to get the colors from?

As you can see, the colors from above are using a special format.

If you’re not familiar with the hex colors you can find a lot of color pickers online just by searching for “Hex Colors” or “HTML Colors”.
Here are a few examples:
