Another way to generate random colors:

var hex = new Array('0','1','2','3','4','5','6','7','8','9','a','b','c','d','e','f');
var ranval = function() {
    return hex[Math.floor(Math.random()*hex.length)];
}
var colorname = function() {
    return "#" + ranval() +ranval() + ranval() + ranval() + ranval() + ranval();
}

// call the colorname();
