  The Ultimate Hover Color Function
  @author Gray Gilmore - http://code.graygilmore.com

  The goal of this Sass function is provide a hover color that works
  with any color on any background. No longer do we need to bundle
  hover color options with our themes, let Sassy McSasserson take care
  of that for you.

  The hover color, seen in this demo as "After" text, must be visible in
  all situations and, hopefully, pass the WCAG 2.0 contrast ratio [1]
  formula (4.5:1).

  [1] http://www.w3.org/TR/2008/REC-WCAG20-20081211/#visual-audio-contrast-contrast

  contrast-ratio() help from @davidkaneda


  ## Usage ##

  a {
    color: $link-color;
    
    &:hover {
      color: hover($background-color, $link-color);
    }
  }

  button {
    background: $button-background;
    color: $button-color;

    &:hover {
      background: hover($background-color, $button-background);
    }
  }

  ## End Usage ##

  @see https://codepen.io/giana/project/full/ZWbGzD

  This pen uses the non-standard Sass pow() function
  https://css-tricks.com/snippets/sass/power-function/
  Using it outside of CodePen requires you provide your own pow() function with support for decimals

  To generate random colors, we're also using a two-variable random() function includded with compass.
