Change Background color of tabs popup opened on click of more button/icon in xamarin forms

Question

I have a Xamarin form for android that I set the background color for tabs at the time of creating the tabs from code behind. The first 4 tabs show exactly the right colors but, the next 3 tabs, under the MORE menu, show a white background. May I get help please on how to change the background and text colors for the additional 3 tabs?

[Background color works well for initial 4 tabs] but does not behaves the same with tabs that are opened on the click of more (https://i.stack.imgur.com/HRZLm.png)

I created a project and used TabbedPage. It shows the same situation happened to you.

Then I tried to Modify its background and text colors by TabbedPageRenderer but failed. There are no relevant override methods to achieve it.

I searched relevant cases about it. You can refer to them:

Case1: How to change name of "More" tab on tabbedPage. It tells about Changing name of "More" by TabbedPageRenderer.

Case2: Background color for more than 5 tabs Xamarin forms. It involved:

From Shell custom render, there is one panel pop up when we click More tab, it is not BottomNavigation bar, I can not find a way to replace this panel or set background color, you can feedback this request on github , I think it is new feature.

It's the source code of Xamarin.Forms.Platform.Tizen, but I did not find the code of Xamarin.Forms.Platform.Android.

In addition, if you can accept this effect: Xamarin tabbed page slide tab bar instead of "More" button. It can help you.
