To change the Tooltip background color you have to use the backgroundTint property and to change the Tooltip text color you have to use a custom android:textAppearance style like in the below example:

<style name="Tooltip" parent="Widget.MaterialComponents.Tooltip">
    <!--This is the Tooltip textAppearance -->
    <item name="android:textAppearance">@style/TextAppearance.Tooltip</item>
    <!--This is the Tooltip Background Color -->
    <item name="backgroundTint">@android:color/holo_orange_light</item>
</style>

<style name="TextAppearance.Tooltip" parent="TextAppearance.MaterialComponents.Tooltip">
    <!--This is the Tooltip Text Color -->
    <item name="android:textColor">@android:color/holo_blue_light</item>
</style>

and you can use the above custom Tooltip Style like below:

<com.google.android.material.slider.Slider
   app:labelStyle="@style/Tooltip"
   android:layout_width="match_parent"
   android:layout_height="wrap_content" />
