title: Default color of mdInput, placeholder
body: <p>Is it possible to change the default color of mdInput placeholder in angular<strong>JS</strong> material ?</p>
  
  <p>HTML code is below</p>
  
  <pre><code>&lt;md-input-container class="header-inputContainer" floatPlaceholder="never"&gt;
      &lt;input class="header-inputBar" mdInput placeholder="荷主" [formControl]="sample" [mdAutocomplete]="autoTxt"&gt;
  &lt;/md-input-container&gt;
  </code></pre>
  
  <p>now it's Grey as you can see " <code>荷主</code> ", but I want to color it white like " <code>Local Development</code> ".</p>

  <p>I managed to change the color when mdInput is focused, but not the default.</p>
