The task is "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."

I found the solution:

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