The Buffer Button Plugin (change color)

Hi! I just installed The Buffer Button plug-in and I love just about everything about it except that the “count” bubble is green, and my blog’s highlight color is orange. Specifically it is #f9ca79. When you move your cursor over the bubble it goes from one shade of green to another. Is there anyone out there who might help me to change it to two shades of orange that match my theme? It’s a small thing, but it would make a big difference to me since my theme is very minimalistic. Thank you.

	if (is_single()) {

		$post = $GLOBALS["post"];
		$the_title = $post->post_title;
		$the_permalink = get_permalink($post->ID);

	require_once("the-buffer-button-admin.php");

}

?>

And here is the admin.php:

`<?php

update_option(“the_buffer_button_display”, $_POST[“display”]);
}

if (isset($_POST[“style”])) {
update_option(“the_buffer_button_style”, $_POST[“style”]);
}

if (isset($_POST[“twitter-username-to-mention”])) {
update_option(“the_buffer_button_twitter_username_to_mention”, $_POST[“twitter-username-to-mention”]);
}

?>
