Stylish Smilies adds CSS classes to text-based emoticons. 
You can then reference these classes in your theme to style each emoticon differently:
<pre><code>.smiley {
/* Applies to all emoticons */
 color: black;
 font-weight: bold;
}

.biggrin {
/* Applies to :D only */
 background: green;
}
</code></pre>
