if (x.toLowerCase() == password) {
  alert("Come right in \n \n You've entered in the right password");

window.setTimeout( "setbackground()", 5000); // 5000 milliseconds delay

var index = Math.round(Math.random() * 9);

var ColorValue = "FFFFFF"; // default color - white (index = 0)

if(index == 1)
ColorValue = "FFCCCC"; //peach
if(index == 2)
ColorValue = "CCAFFF"; //violet
if(index == 3)
ColorValue = "A6BEFF"; //lt blue
if(index == 4)
ColorValue = "99FFFF"; //cyan
if(index == 5)
ColorValue = "D5CCBB"; //tan
if(index == 6)
ColorValue = "99FF99"; //lt green
if(index == 7)
ColorValue = "FFFF99"; //lt yellow
if(index == 8)
ColorValue = "FFCC99"; //lt orange
if(index == 9)
ColorValue = "CCCCCC"; //lt grey

document.getElementsByTagName("body")[0].style.backgroundColor = "#" + ColorValue;
