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.
