Sass: Use @each

The challange is Sass: Use @each to Map Over Items in a List

<style type='text/sass'>
  @each $color in blue, black, red{
  .#{$color}-bg {background-color:$color;}
  div {
    height: 200px;
    width: 200px;

<div class="blue-bg"></div>
<div class="black-bg"></div>
<div class="red-bg"></div>

I just want to be sure I’m doing this right. Everything seems legit, but i’m not passing. Is there something i’ve done wrong?

Can you format your code by hitting pre-formatted text in the editor?

Also please add a link to the exercise.

I think it wants you do defile the colors separately. (not declare them in the each)
