@yurua Hi, you have to add to your themes.xml some items. You can choose whatever you want to use.

This is the code you have to add:

    <style name="<Your app theme name>" parent="Theme.Material3.DayNight.NoActionBar">
        <item name="android:colorBackground">@color/high_contrast_background</item>
        <item name="android:colorForeground">@color/high_contrast_foreground</item>
        <item name="android:colorPrimary">@color/high_contrast_primary</item>
        <item name="android:colorPrimaryDark">@color/high_contrast_primary_dark</item>
        <item name="android:colorAccent">@color/high_contrast_accent</item>
    </style>

And you also have to add these items to the colors.xml

    <color name="high_contrast_background">#FF000000</color>
    <color name="high_contrast_foreground">#FFFFFFFF</color>
    <color name="high_contrast_primary">#FF000000</color>
    <color name="high_contrast_primary_dark">#FF000000</color>
    <color name="high_contrast_accent">#FF000000</color>

For example, if you just want to change the background color, you will only need to add the android:colorBackground to the themes.xml

You're free to use the ones that you want. If you have another question leave it here!
