Passing "1px solid" as mixin variable not passing challenge

I'm passing $size and $color: 1px solid as parameters for a mixin. But the Challenge still fails saying I need to set the border to 1px solid. What am I doing wrong?

style.scss 
@mixin square($size, $color: 1px solid) {
  height: $size;
  width: $size;
  border: $color black;
}

the only part of the border rule that is an argument to the mixin is color, the width and style are fixed here, so they go in the mixin body and will not be passed in. then when it asks to make black the default, that goes in the top line after the colon after $color. so now the mixin takes a size and a color, with black the default, then in the body, width and height are size, and the border will be 1px solid (color).
