Change wpadminbar (top bar) color of wordpress admin panel

So here is how we can change the wordpress adminbar (top bar color).

We need to add the following to functions.php. I added them to the end of the file.

add_action('wp_head', 'change_bar_color');
add_action('admin_head', 'change_bar_color');
function change_bar_color() {
?>
