Answer 1

Put it in your style.xml in AppTheme:

<!-- android:textColorSecondary is the color of the menu overflow icon (three vertical dots) -->
<item name="android:textColorSecondary">@color/white</item>

Answer 2

You can change the image used for it using the following style declaration.

<style name="MyCustomTheme" parent="style/Theme.Holo">
<item name="android:actionOverflowButtonStyle">@style/MyCustomTheme.OverFlow</item>

</style>

<style name="MyCustomTheme.OverFlow">
<item name="android:src">@drawable/my_overflow_image</item>

</style>
