  var colorarray=[rndred, rndgreen, rndblue];
  var hexcolor="#";
  for(i=0;i<3;i++) {
    hexcolor=hexcolor +""+ converttohex(Math.floor(colorarray[i]/16));
    hexcolor=hexcolor +""+ converttohex(colorarray[i]%16);
  }
  document.getElementById("myDiv").style.backgroundColor=hexcolor;
}
function converttohex(num) {
  switch (num) {
    case 10: return "A";
