I did it like this in 4.0.7:

<form action="forum.php" method="get" id="footer_select"><select style="background-color:#F2F6F8;" name="styleid" onchange="switch_id(this, 'style')"><optgroup>
<option value="" select="selected">Colors</option>
<option value="1">-- Original</option>
<option value="17">-- Gray</option>
<option value="15">-- Ice</option>
<option value="13">-- Pink</option>
<option value="19">-- Orange</option>
<option value="16">-- Green</option>
<option value="24">-- XGreen</option>
<option value="22">-- Red</option>
<option value="7">-- Dark Red</option>
<option value="36">-- Lime</option>
<option value="3">-- Dark Lime</option>
<option value="12">-- Blue</option>
<option value="2">-- Dark Blue</option>
<option value="21">-- Purple</option>
<option value="35">-- Dark Purple</option>
</optgroup>
</select>
</form>

Of course you have to use your own style names and style #s
