title: How can I change the color of the ion-title?
body: <p>I try to change color of the ion-title in ionic 2.</p>
  
  <p>I have this following code:</p>
  
  <pre><code>&lt;ion-header&gt;
    &lt;ion-navbar&gt;
     &lt;ion-title primary&gt;Title&lt;/ion-title&gt;
    &lt;/ion-navbar&gt;
  &lt;/ion-header&gt;
  </code></pre>
  
  <p>The color of the <code>ion-title</code> don't change. I try several things like:</p>
  
  <pre><code>&lt;ion-title color="primary"&gt;Title&lt;/ion-title&gt; 
  &lt;ion-title&gt; 
      &lt;p primary&gt;Title&lt;/p&gt;
  &lt;/ion-title&gt;
  </code></pre>
  
  <p>With the second I have the title in the right color, but the header is big. So I add this in the variables.scss:</p>
  
  <pre><code>$toolbar-ios-height: 5rem; // ios
  $toolbar-md-height: 5rem;  // android
  </code></pre>
  
  <p>But nothing change.Does anyone have a solution? Or do I have to use the <code>p</code> or <code>h</code> tag to change the color?</p>
