I received mirror samples (not the touch foil for the moment).
Tried Mirastar, MirroView, and ChromeSpy.
MirroView permit to view any colour clearly, and without metallic coat, should be compatible with touch foils. But reflection is a little poor, and in dark room, event with luminosity at 0 we can see the black screen. So, should be used for touch capacity and in very light room.
ChromeSpy has better reflection, but a little “brown”. Much better in dark room, in light room it needs a good luminosity behind. Great for white text on black screen, but not for colours.
Mirastar has the best reflection, and work really great in dark room. Like ChromeSpy, it needs a higher luminosity in light room. Great for white text on black screen, not for colours too.
So, if we really need touch capacity or colours, MirroView is the best, but a little sacrifice on reflection (not really useful as a real mirror)
If we need a better reflection, no colours behind, and no touch screen, Mirastar is the winner. Maybe need an adaptative script/screen to adjust luminosity in function of room light.
ChromeSpy is near Mirastar, let a little more colours passed, but with a little worst reflection.
