Code challenge: creating loops with @for and @each.

The challenge states :

Use an @each loop to set the variable "$color" to the color red, then blue, and finally green. Use the loop to create three classes: ".red_box", ".blue_box", and ".green_box". The background color for each class should be set to the corresponding color.

@each $color in red, blue, green {
    .color.#{$color} {
    background-color: $color;
  }
}

I believe I'm doing somethin wrong by passing the background-color the value of the variable $color and I beleive I need to place ._box somewhere but I'm a little confused with this one.

The following error message is received: "Bummer! There should be a .red_box class with a red background. Did you set up the loop correctly?"

Any help would be greatly appreciated.

Many thanks. Gareth

You didn't interpolate the class selector correctly.

@each $color in red, blue, green{
    .#{$color}_box{
    background-color:$color;
  }
}
