This script changes the orange bar across the top to a different color, of your choice, it includes 5 preset colors, and it is easy to choose which one you want, and its also not hard to program your own colors.

Just add this to the bottom of the script. If you want to keep all the color variables together, put the "var color = "mycolor";" at the top with the other colors so if you end up with like 20 colors, your not scrolling through the script to find them.

var color = "mycolor";

if(color=="mycolor"){
var head = document.getElementById('header');
head.style.backgroundColor = '#HEXCODEHERE';
var images = document.getElementsByTagName("img");
for (var i = 0; i < images.length; i++) {
  var elem = images[i];
  if (elem.src == "http://static.userscripts.org/images/userscripts.org.png?1173055699")
    elem.src = "YOUR IMAGE URL HERE";
}}
