title: Change color of TimePicker (RadialTimePickerView)?
body: <p>How do I change the number/picker-color of the TimePicker/RadialTimePickerView? I can see, that the RadialTimePickerView sets its color internal by using </p>
  
  <pre><code>final int numbersTextColor = a.getColor(R.styleable.TimePicker_numbersTextColor,
              res.getColor(R.color.timepicker_default_text_color_material));
  </code></pre>
  
  <p>I tried adding a <code>timepicker_default_text_color_material</code> item to the colors.xml, but this didn't work out.</p>
  
  <p>The black numbers and the blue picker should be white:
