Anti-Fingerprinting: Fake background colors if they are unneeded

[MatsG23]

Material You generates color palettes based on your wallpaper. Every app can access the background colors APIs. The issue: this makes a user very unique if he uses an uncommon wallpaper (amount of uniqueness can be tested using this app).

I suggest that the wallpaper colors are faked to #000000 (colors of the black GrapheneOS default wallpaper) if the user chose a theming color palette not based on the wallpaper colors (see screenshot)

I would love to have a privacy option to spoof black for these api calls.

Would be a realy nice feature... Many of us use black wallpaper only because of that

I second this request. Using GOS stock wallpaper because of this. Not that I don't like it, but would be great to use any wallpaper without compromising the privacy.

This only would make sense if you restrict access to the wallpaper as well. At this point any app has access to the wallpaper picture anyway. To me that seems like a bigger deal

Wouldn't it be good to also just give them the colors for the wallpaper theme chosen in the settings (default theme is derived from wallpaper, but even when changing the theme to another wallpaper based theme they can see both lock screen and home screen wallpaper colors) when using a wallpaper color theme? So when they look at the lock screen and home screen colors they always only see the chosen wallpaper theme's colors, and when choosing non-wallpaper themes ("Other colors") black can be given as the wallpaper colors as this issue says.
