How to set an ImageButton background color to a specific color of a theme that could be adapted to the night mode?

I want to find a way to set the background color of an ImageButton to a color that I defined in my themes and which changes with day or night mode.

Is this possible?

Here is the color that I want (colorPrimary) in the themes file:

<item name="colorPrimary">@color/blue_900</item>

Thank you very much.

According to Material Design guidelines (see here),

1. In styles.xml, inherit from a DayNight theme.

    <style name="Theme.MyApp" parent="Theme.MaterialComponents.DayNight">
        ...
        ...
    </style>

2. Create a new colors.xml file under the values-night directory.

3. In values\colors.xml,

    <color name="primary_color">{your-light-theme-color-here}</color>

In values-night\colors.xml

    <color name="primary_color">{your-dark-theme-color-here}</color>

4. In styles.xml,

    <style name="Theme.MyApp" parent="Theme.MaterialComponents.DayNight">
        <item name="colorPrimary">@color/primary_color</item>
        ...
    </style>

5. Set this theme in your AndroidManifest.xml

    <application
        ...
        android:theme="@style/Theme.MyApp">
    </application>

I feel this is the most guideline-appropriate and efficient way.
