Light Silver as a backer.... yes. On top LS will result in a loss of gain because despite the "Silver" designation, it's really just a specific shade of Light Gray. If a sheen is added it becomes more "silvery" but then also becomes less desirable as a screen material.
Using any brighter / Darker material behind another opposite is used to increase gain or increase contrast. But any overly reflective material might cause adverse interference with the topmost image by adding a secondary image to the equation that does not blend well. Just the same, too dark a backer will crush down too much reflective tendency on the top surface...although that is not the case of a uber-lumen PJ is employed, or the ratio of Screen size to Lumen output is favoring the PJ. Then, the top surface simply becomes more "High Contrast" oriented.
Spandex's light permeability is such that anything behind it that is lighter or darker has a gross effect. It's not the same as when a almost
opaque surface is using a highly reflective material as a backer such as Bright Aluminum, a 2nd Surface Mirror, or a bright glossy white. Those surfaces overt reflective tendencies are suppressed by the density of the topmost surface just enough to allow them to be an advantage, not a detriment.
But as stated just prior above, experimentation can result in a revelation...which can equate to an exclamation of elation, that has reverberations across generations of .......DIY'ers.
It could even result in veneration and a personal canonization.
