How can I change the CheckBox focus color on Android?

Question

I want to change the checkbox "outline" color, which is visible when focusing the checkbox in order to improve the visibility of the currently focused item when using the app with a keyboard or directional pad. How can I do that?

Image of what I mean: Focused CheckBox on Android

Edit: After finding the correct wording ("ripple color") for what I mean, I managed to change it with:

<item name="colorControlHighlight">#00f</item>

But this only applies to unchecked checkboxes. Does anybody know how to apply it to all (also checked) checkboxes? Image of colorControlHighlight effect on checked and unchecked checkboxes

This works: define an own ripple ripple_bg.xml:

<ripple xmlns:android="http://schemas.android.com/apk/res/android"
        android:color="@color/accent_26" />

And set it as background (globally):

<resources>
    <style name="AppTheme" parent="Theme.AppCompat.DayNight">
        <!-- ... -->

        <!-- custom checkbox style to improve visibility on special (TV) devices -->
        <item name="android:checkboxStyle">@style/MyCheckBoxStyle</item>
    </style>

    <style name="MyCheckBoxStyle" parent="Widget.AppCompat.CompoundButton.CheckBox">
        <item name="android:background">@drawable/ripple_bg</item>
    </style>
</resources>
