The test project
In the UWP app.
If I set the BarTextColor to a light color, and then add toolbar items, the items in the secondary menu take on the color of the BarTextColor. As the color of the background of the toolbar secondary menu cannot be controlled, this should not happen.
Typically, I would set the BarBackgroundColor to a nice dark (Xamarin Blue) color, and the BarTextColor to a light (White) color. This causes issues as the secondary menu retains the light grey, but the text gets the new white.
I am thinking this line (did five seconds of research):
I don't think it would be good to set the background color, as this does not change the color of the menu. TO do that, I think you might need to create a new style for the presenter: CommandBarOverflowPresenterStyle
I will attach screenshots of what I mean.

The bar background is blue with a text color of white.

The bar background is red, text white.
Then the AppBarButton is green with white text.
I also noticed that the hover/hot color of the secondary items is Black. So, no matter the color I set the items, they hover at black. If the menu background is changed, then features need to be added to change the text, hot text and the selection colors.
Should be fixed in 2.3.4-pre2
I have checked this issue and observed that this issue has been fixed with Xamarin.Forms 220.127.116.11-pre1.
Hence closing this issue.
