You might need to take a look at the jQuery plugin jqtransform.

I have personally tested it and its works in IE-7.

Very low quality question.. but here goes..

you can style it in an external CSS by using :

option {color:green;}

you can use inline-styling like this :

<option style="color:green;">

Here is the links for a great css and jQuery for the select option tag:

tyle-select-box-using-only-css.
custom-styling-of-the-select-elements.
harvesthq.github.

Hope these links will help you.
