title: textColorHint is ignored as hint text color is always colorAccent
body: <p>I am trying to create a text field layout similar to <a href="https://www.google.com/design/spec/patterns/errors.html#errors-user-input-errors" rel="nofollow">material design - error user input</a>, but I am facing an issue with the hint color. The Material Design guidance states the hint color for a light theme should be </p>
  
  <blockquote>
    <p>Hint and helper text: #000000 with 38% opacity</p>
  </blockquote>
  
  <p>which made me add <code>&lt;item name="android:textColorHint"&gt;@color/hint_color&lt;/item&gt;</code> to my <code>AppTheme</code> and <code>&lt;color name="hint_color"&gt;#61000000&lt;/color&gt;</code> to my <code>colors.xml</code>. </p>
  
  <p>However, the hint color always the same as my <code>&lt;item name="colorAccent"&gt;@color/accent&lt;/item&gt;</code> (part of <code>AppTheme</code>) which is currently set to light blue. </p>
  
  <p>So how can I fix this? I have tried to set the hint color directly on the <code>TextInputLayout</code> and <code>AppCompatEditText</code> but no luck.</p>
  
  <p>Thanks, </p>
