Cannot change Ionic set colors

ionic-v1

I am having trouble changing the ionic positive color. Here is how I have tried to change the color to teal.

Here is the code for my files:
index.html

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
    <title></title>
    <link href="lib/ionic/css/ionic.css" rel="stylesheet">
    <link href="css/style.css" rel="stylesheet">

    <!-- IF using Sass (run gulp sass first), then uncomment below and remove the CSS includes above
    <link href="css/ionic.app.css" rel="stylesheet">
    -->

    <!-- ionic/angularjs js -->
    <script src="lib/ionic/js/ionic.bundle.js"></script>

    <!-- cordova script (this will be a 404 during development) -->
    <script src="cordova.js"></script>

    <!-- your app's js -->
    <script src="js/app.js"></script>
    <script src="js/controllers.js"></script>
  </head>

  <body ng-app="starter">
    <ion-nav-view></ion-nav-view>
  </body>
</html>

Ionic.app.scss

/*To customize the look and feel of Ionic, you can override the variables
in ionic's _variables.scss file.

For example, you might change some of the default colors:

$light:                           #fff !default;
$stable:                          #f8f8f8 !default;
$positive:                        #387ef5 !default;
$calm:                            #11c1f3 !default;
$balanced:                        #33cd5f !default;
$energized:                       #ffc900 !default;
$assertive:                       #ef473a !default;
$royal:                           #886aea !default;
$dark:                            #444 !default;
*/

$positive:                        teal !default;
// The path for our ionicons font files, relative to the built CSS in www/css
$positive
$ionicons-font-path: "../lib/ionic/fonts" !default;

// Include all of Ionic
@import "www/lib/ionic/scss/ionic";

Here is updated version of my index.html file. I ran gulp sass and removed the css includes.

<!-- IF using Sass (run gulp sass first), then uncomment below and remove the CSS includes above -->
<link href="css/ionic.app.css" rel="stylesheet">


<!-- ionic/angularjs js -->
<script src="lib/ionic/js/ionic.bundle.js"></script>

<!-- cordova script (this will be a 404 during development) -->
<script src="cordova.js"></script>

<!-- your app's js -->
<script src="js/app.js"></script>
<script src="js/controllers.js"></script>
