title: Vuetify button colors are not working
body: <p>I'm using webpack to compile my vuejs project and use the vuetify framework but I can't get the colors to work. For example this:</p>
  
  <pre><code>&lt;v-btn color="error"&gt;Error&lt;/v-btn&gt;
  </code></pre>
  
  <p>Does not produce the red error button, instead it's just the white one. I include all the files using this:</p>
  
  <p>main.js</p>
  
  <pre><code>import Vuetify from 'vuetify'
  Vue.use(Vuetify)
  import '../node_modules/vuetify/dist/vuetify.min.css'
  </code></pre>
  
  <p>and App.vue</p>
  
  <pre><code>&lt;style lang="stylus"&gt;
    @require '../node_modules/vuetify/src/stylus/main'
  &lt;/style&gt;
  </code></pre>
  
  <p>Could someone tell me what I'm forgetting?</p>
