Is it possible to change color of specific option in Dropdown Lists?

Hello! I have a simple dropdown list in my game with ID set as drop1 and class dropdownlist.

This list has 10 different options, but some of them have more impact than others, so I'm trying to change the color of those ones to be highlighted.

I just can't figure out how to do it. Does someone knows any way to achieve that?

Thank you all!

You can use CSS. developer.mozilla.org/en-US/docs/Web/CSS/:nth-child

<style type="text/css">
 #myForm select option:nth-child(odd) {
 color:black;
 background:yellow;
 }
 #myForm select option:nth-child(even) {
 color:white;
 background:blue;
 }
 #myForm select {
 background:green;
 color:orange;
 }
 </style>
