Did you set the styles to your DIVs? If you just run this in html file, the height of those DIVs is zero, so you can't see them. Try to give the DIVs a height.

For this, case a div hight was specified its part of a refactor challenge.

Try removing the last ',' in randomColor()

function randomColor() {
  var color = 'rgb('
  color += randomRGB() + ',';
  color += randomRGB() + ',';
  color += randomRGB();
  return color;
}
