On Package.Appmanifest we can define SplashScreen background color that is used for:
1) SplashScreen background - pretty obvious
2) to fit the space between new window border and not (yet) resized content when user is resizing the app window
If you don't know what I am writing about under 2) - just run Xbox app (or any other written with UWP), grab window border and then quickly move the window border back and forward.
The problem is that I would like to have two separate colors for that. Color A for SplashScreen background and Color B that would be visible during this resize. Apparently they are the same colors by default.
Is there any way to declare different colors for this two places within the app or any way to change the SplashScreen background color at runtime (to have the Color A during launch time and then after app has already lunched I could override this color with Color B to get the behaviour I need)?
