How I refactored

var html = '';
var red;
var green;
var blue;
var rgbColor;

function randomColor() {
  return Math.floor(Math.random() * 256 );
}

for (var i = 0; i < 10; i++) {
  red = randomColor();
  green = randomColor();
  blue = randomColor();

  rgbColor = 'rgb(' + red + ',' + green + ',' + blue + ')';
  html += '<div style="background-color:' + rgbColor + '"></div>';
}

document.write(html);

Good job! :+1:

Your solution has many of the elements of the one Dave shows in the second solution video.

Nice! The next step might be to remove the color variables entirely and just call the function directly in the html variable assigning like: html += '<div style="background-color:rgb(' + randomColor() + ',' + randomColor() + ',' + randomColor() + ');" ></div>'; See if you can get the whole thing down to 8 lines..
