title: Sass color variable not working inside darken()
body: <p>I've got list of colors and I would like to use darken() on them like so:</p>
  
  <pre><code>$innerPagesBgColors: "#6B46C1", "#2980B9", "#FD5456", "#000";
  
  .foo {
      color: darken(nth($innerPagesBgColors, 3), 5%);
  }
  </code></pre>
  
  <p>But I get this error:</p>
  
  <blockquote>
    <p>$color: "#FD5456" is not a color for `darken'</p>
  </blockquote>
  
  <p>I tried interpolating the nth() portion but that didn't help either.</p>
