Why Does My Solution Not Work?

var html = '',
rgbColor;

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

for(i = 0; i < 10; i++){
  rbgCreator();
  html+= '<div>' + rgbColor + '</div>';
}

document.write(html);

I followed along with another person's solution, with a slight tweak in how I made mine (I think they styled their div's). Can somebody please help me understand why my solution will not generate the desired outcome? Thanks!
