I did something completely different but it works absolutely fine.

What i did:

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

function doColor() {
red = Math.floor(Math.random() * 256 );
green = Math.floor(Math.random() * 256 );
blue = Math.floor(Math.random() * 256 );
rgbColor = 'rgb(' + red + ',' + green + ',' + blue + ')';
html += '<div style="background-color:' + rgbColor + '"></div>';

for (var i = 1; i < 10; i += 1 ) {

Your code several times inside your loop redefining var red, green, blue; and rgbColor and print out nothing. What the point? If your tip was to redefine this variables you pass the test. If you need answer how to make it working right I can show you up my solution. =)
