Aide modification javascript (skittlish : WP)

Bonjour,
Voila je vais essayé de vous expliqué au mieu mon probleme : J'ai crée un blog sous wordpress 2.8 et j'ai ajouté le theme Skittlish .
Ce theme propose un changement de couleur de la sidebar selon notre choix.. Mais celle par default est "orange" Or je trouve ca tres moche.. Il y a un script java qui controle tout ca il me semble avec des histoire de cookies mais je comprends vraiment pas tres bien.. Voici le code java :

/* base class extensions */
String.prototype.trim = function() {
return this.replace(/^\s+/, '').replace(/\s+$/, '');
}
Array.prototype.indexOf = function(elem) {
for (var i=0; i<this.length; i++) {
if (this[i] == elem) return i;
}
return -1;
}

/* dom helpers */
function hasClass(elem, name) {
var arr = elem.className.split(' ');
if (arr.indexOf(name) != -1) {
return true;
}
return false;
}
function addClass(elem, name) {
var arr = elem.className.split(' ');
if (arr.indexOf(name) == -1) {
arr.push(name);
elem.className = arr.join(" ");
}
}
function removeClass(elem, name) {
var arr = elem.className.split(' ');
var arr2 = [];
for (var i=0; i<arr.length; i++) {
if (arr[i] != name) {
arr2.push(arr[i]);
}
}
elem.className = arr2.join(" ");
}
// we want to touch the className only once
// yeah, it's not dry :p
function replaceClass(elem, old_class, new_class) {
var arr = elem.className.split(' ');
var arr2 = [];
for (var i=0; i<arr.length; i++) {
if (arr[i] != old_class) {
arr2.push(arr[i]);
}
}
arr2.push(new_class);
elem.className = arr2.join(" ");
}

/* cookie helpers */
function setCookie(name, value, permanent) {
var expires = '';
if (permanent) {
expires = '; expires=' + (new Date()).toGMTString().replace(/20\d\d/, 2020);
}
document.cookie = name+"="+value+expires+"; path=/";
}
function getCookie(name) {
var i, crumbs, crumb;
crumbs = document.cookie.split(';');
for (var i=0; i<crumbs.length; i++) {
crumb = crumbs[i].trim();
if (crumb.indexOf(name + "=") == 0) {
return crumb.substring((name + "=").length);
}
}
return '';
}

/* el customizer */
function loadPreferences() {
var cookie = getCookie('skittlish');
if (cookie == '') {
cookie = 'fixed orange';
}
document.getElementsByTagName('body')[0].className = cookie;
}
window.onload = function() {
var o = document.getElementById("options");
var lis = o.getElementsByTagName("LI");

for (var i=0; i< lis.length; i++) {
li = lis[i];
parts = li.id.split("_");
//li.title = parts[1] + ": " + parts[2];

li.onclick = function() {
var body = document.getElementsByTagName('BODY')[0];
var new_option_group = this.id.split("_")[1];
var new_option = this.id.split("_")[2];
if (new_option_group == 'size') {
if (new_option == 'fluid') {
replaceClass(body, 'fixed', 'fluid');
} else {
replaceClass(body, 'fluid', 'fixed');
}
} else {
var colors = 'blue,cyan,green,orange,pink,red,violet'.split(',');
var current_color = '';
for (var i=0; i<colors.length; i++) {
if (hasClass(body, colors[i])) {
current_color = colors[i];
break;
}
}
if (new_option != current_color) {
replaceClass(body, current_color, new_option);
}
}
setCookie('skittlish', body.className, true);
return false;
}

}

}


Si quelqu'un sait comment modifier ce code afin que la couleur par default soit Cyan et non plus orange je lui en serait tres reconnaissant !

Merci de vos réponses, Dan
