How to change color or drawable of Spinner arrow

Just want to change the color of the Spinner arrow (@color or @drawable)

This is the only code that did something and it make the drawable the entire background of the spinner. (I've tried many other ideas with no luck)

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
...
<item name="android:spinnerStyle">@style/SpinnerColor</item>
</style>

<style name="SpinnerColor" parent="Base.Widget.AppCompat.Spinner">
    <item name="android:background">@drawable/ic_add_white_24dp</item>
</style>

Anything helps thanks!
