This is how i set style (color here) of all of the options of a select list using jQuery.
In my case i had select options like this:
<select id=”select_list_id”>
<option value=”#595959″>Grey</option>
<option value=”#000000″>Black</option>
<option value=”#036″>Blue</option>

<option value=”#632423″>Red</option>
<option value=”#403152″>Purple</option>
<option value=”#E36C0A”>Orange</option>
</select>
Follwoing the jQuery code i used to set color of options above:
$(document).ready(function(){
$('#select_list_id option', this).each(
function () {
$(this).css({'color':$(this).val()});
}
)
});
