title: android Theme.Holo.Dialog changing blue lines to orange
body: <p>Default color for lines on Android theme Theme.Holo.Dialog are blue.
  I'd like to know how to change this to any other color.
  Orange in my case.</p>
  <p>I can change text or background etc.. overriding the theme with a custom style.xml</p>
  <pre><code>   &lt;style name=&quot;Theme.MyTheme&quot; parent=&quot;@android:style/Theme.Holo.Dialog&quot; &gt;
          &lt;item name=&quot;android:textColor&quot;&gt;@color/coloroscuro&lt;/item&gt;
          &lt;item name=&quot;android:textColorHint&quot;&gt;@color/coloroscuro&lt;/item&gt;
     &lt;/style&gt;
  </code></pre>
  <p>but I don't know which property manages the color of the lines.</p>
  <p>I mean the blue lines that the theme has by default like the ones shown on this other question:</p>
