BlackRiverFalls said:I tried something similar a few years ago with a couple of old dressing table mirrors. The culmulative reflections took on a distinct greenish quality like looking into a murky lake, no idea if that was down to an otherwise unaparent tinting in the glass, the imperfection of the silvering, or some sort of refractive index issue.
my bet's on tinting in the glass, as most glass does appear to be blueish if you look at it side-on.
