Link color mixin... this might be either really useful or really stupid.

link-mixin.scss

// These are global colors

$lcolor: #7ab4e5;
$vcolor: #7ab4e5;
$hcolor: #e62c25;
$acolor: lighten($hcolor, 10%);
$fcolor: $hcolor;
$link-transition: .15s color ease-in-out

// Mixin will let you override globals... or not, depending on what you pass to it.

@mixin links($link:"", $visited:"", $hover:"", $active:"", $focus:"", $transition:"") {
  &:link { 
    @if $link != ""       { color: #{$link}; }
    @else                 { color: $lcolor; }
  }
  &:visited { 
    @if $visited != ""    { color: #{$visited}; }
    @else                 { color: $vcolor; }
  }
  &:hover { 
    @if $hover != ""      { color: #{$hover}; }
    @else                 { color: $hcolor; }
  }
  &:active { 
    @if $active != ""     { color: #{$active}; }
    @else                 { color: #e62c25; }
  }
  &:focus { 
    @if $focus != ""      { color: #{$focus}; }
    @else                 { color: $fcolor; }
  }
  @if   $transition != "" { @include transition(#{$transition}); }
  @else                   { @include transition($link-transition); }
}

// Usage - all arguments are optional
a { @include links($link: red, $visited: blue);}
