How to change the background/text color of a layout when daynight theme is used

Question

I'm using Theme.AppCompat.DayNight and I want to customize a certain layout background and text color to change depending on whether it's day or night mode .

Here's what I tried so far:

<style name="AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/primaryDarkColorAmber</item>
    <item name="colorPrimaryDark">@color/primaryDarkColorAmber</item>
    <item name="colorControlActivated">@color/primaryDarkColorAmber</item>
</style>

<style name="PopUpTheme" parent="AppTheme">
    <!-- layout custom theme there's no darkBackground value...!! -->
    <item name="android:background">@color/popup_background</item>
</style>
