Use style sheets to color the background of your drop downmenus:
Use code like this in your <head> tags:
<style type="text/css">
<!--
select { background-color: #FF0000; font-family: Verdana, Arial, Helvetica,
sans-serif; color: #FFFFFF; font-weight: bold}
-->
</style>
Here is how you can color the scroll bars:
<style>
<!--
BODY{
scrollbar-face-color:'';
scrollbar-base-color:#21436b;
scrollbar-arrow-color:#FFFF00;
scrollbar-track-color:'';
scrollbar-shadow-color:'';
scrollbar-highlight-color:'#336699';
scrollbar-3dlight-color:'';
scrollbar-darkshadow-Color:'';
}
-->
</style>
