Dim parts of UI

[KOLANICH]

Some apps are too bright for amoled screen because their devs dont care about it and because "material design" is meant to be screen burningly bright. Some of that apps have fixed ui elements positions. So, can it be possible to
1 make screenshot
2 replace colors of needed piece, unneeded pieces redraw in transparent color.
3 draw it over screen when activity is active.
