You can customize the background color using the android:popupBackground attribute.

  <!-- Popup Menu -->   
  <style name="MyPopup" parent="@style/Widget.MaterialComponents.PopupMenu">
    <item name="android:popupBackground">@color/custom</item>
  </style>

You can configure globally this style in your app theme using the popupMenuStyle attribute:

  <!-- Base application theme. -->
  <style name="AppTheme" parent="Theme.MaterialComponents.Light">
     ....
    <item name="popupMenuStyle">@style/MyPopup</item>
  </style>

Just use:

PopupMenu popup = new PopupMenu(this, anchor);
popup.getMenuInflater().inflate(R.menu.custom_menu, popup.getMenu());
popup.show();

Currently PopupMenu uses colorOnPrimary to define the textColor. To change it you have to define a textAppearance:

  <style name="MytextAppearanceLargePopupMenu" parent="@style/TextAppearance.MaterialComponents.Subtitle1">
    <item name="android:textColor">@color/colorAccent</item>
  </style>

and then in your app theme adding this attribute:

  <!-- Base application theme. -->
  <style name="AppTheme" parent="Theme.MaterialComponents.Light">
    <item name="textAppearanceLargePopupMenu">@style/MytextAppearanceLargePopupMenu</item>
  </style>

Add popupMenu style to ur AppTheme:

<style name="AppTheme" parent="android:Theme.Light">
    <item name="android:popupMenuStyle">@style/PopupMenu</item>
</style>

<style name="PopupMenu" parent="@android:style/Widget.PopupMenu">
    <item name="android:popupBackground">@android:color/white</item>
</style>

Now in your manifest file

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">
.............
</application>
