I'm wondering what materials would block visible light (emitted from LEDs, for example) but would not impede IR signals or Bluetooth.
Context: I'd love to block all the blinky lights on my home theater setup without invalidating any of my remotes and PS4 controllers (or wifi devices). Ideally I'm looking for a fabric of some sort, but open to other suggestions.
I'm thinking it would be cute to install a pull curtain over the part of my shelving where I want to block the visible lights, thus why I'm inquiring after fabrics. If there's a glass or other material that might work, then I might consider a door of some sort.
Any help/insight would be appreciated. Note that I am aware of IR repeaters and am not interested in installing one. Plus my understanding is that it wouldn't help at all with my PS4 controllers.
EDIT: Many have suggested I just "tape" over the lights themselves. I really would prefer not to do this, as I find value in being able to see the lights easily when I need to debug an issue. For example, one piece of equipment is an HDMI switcher where the lights indicate which input source is currently selected; it doesn't switch automatically with the Apple TV I have connected to it, so I would need to see the lights to determine if I need to switch the input. I need to do this before consuming media, not during, thus why I'm interested in a fabric or a door that can conceal the lights temporarily. Another item in this space is my cable modem, so same deal: if my internet is acting wonky, I want to see those lights easily. But if my internet is fine, I don't want to see them while watching a movie or playing PS4.
