+
+    'android:windowBackground' is the background color of the alert dialog.
+        If not overridden, the background color of the parent theme 'android.R.style.ThemeOverlay_Material_Dialog' is used.
+
+    'R.attr.ytBaseBackground' is the background color in YouTube settings.
+        'R.color.yt_white1' color is used in light theme, and the 'R.color.yt_black3' color is used in dark theme.
+
+    'android:windowIsTranslucent' makes the dialog window transparent.
+
+    'android:background' needs to be transparent for the 'contextual action bar' to be displayed properly.
