This is my refactoring solution, comments please :)

var html = '';
var getRandomColor = function() {
  var red      = Math.floor(Math.random() * 256 );
  var green    = Math.floor(Math.random() * 256 );
  var blue     = Math.floor(Math.random() * 256 );
  var rgbColor = 'rgb(' + red + ',' + green + ',' + blue + ')';

  return rgbColor;
};

for (i = 0; i < 10; i++) {

html += '<div style="background-color:' + getRandomColor() + '"></div>';

}; 
document.write(html);
