What's the most ideal thing to use as the "screen" on the background of a concert stage, that is gonna be lit form behind with whatever shapes and patterns?
And what color is it, matt white? matt black? Are there special cloths that would have minimal bleeding and maximum illuminicity (if that's a word)?

Before (until about 2016) it was an array of projectors with particular lenses so they would be placed as far back as possible. These days they are using immense RGBW led panels made of smaller panels (say for example 160x120) linked together, with a controller that streams the video. A lot of leds and one big FPGA per board to handle the signalling of the portion of the image. i think mike (mikeselectrisstuff) works in that area?

No, I mean backlit, Light projected from behind the stage, shining trough the "screen".

A scrim is fairly common theater equipment.

Yeah well what material is used for the screen?
I would think a white material wouldn't be ideal since it would illuminate from the stage lights and you wouldn't see the rear projection onto it.
But also a black material would be hard to illuminate in the first place, so what does work?

Nevermind, apparently Skrims aren't just fancy curtains, they're designed so they also have like a "one way mirror" effect in a way.
