For testing, I installed an [early preview][1] to my web app using
Firefox Aurora on Android. A shortcut on the home screen has been
created.
When I tap that shortcut, then first I see a start screen with the app's
icon and a load animation (spinning circle). The background color of
this screen seems to vary from app to app. In the case of my app, it's
an ugly yellowish green.
How is the background color of that start screen determined?
Can the start screen's background color be specified, e.g. via the web
app's manifest?
