How to change the change Cancel and Ok buttons' color in the picker?

I'm using a custompicker in my app and I need to change the cancel and ok buttons' color. I recently changed the whole theme of timepicker and datepicker for android by adding this code to the style file:

 <item name="android:datePickerDialogTheme">@style/AppCompatDialogStyle</item>
    <item name="android:timePickerDialogTheme">@style/TimePickerTheme</item>

item name="colorAccent">#039BE5</item>
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">wrap_content</item>
  </style>
  <style name="TimePickerTheme" parent="Theme.AppCompat.Light.Dialog">
    <item name="colorAccent">#039BE5</item>
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">wrap_content</item>
  </style>

Is that a similar code that I can add for the picker?
