Or likewise say you DO want them to show during a movie? Regarding the purple tones, is that painted of controlled with lighting? Can you make it so that no purple shows up or control the brightness of it? Thanks.
It's a glow paint which is also a reactive material which Jeff uses on all of his murals. I have fluorescent lights in my soffit and a large fluorescent "stage light" which I use to charge the ceiling. Any normal fluorescent would light it, but the black lights at the correct wavelength, react to the paint as well, which makes it visible before it is charged. When the black lights are first turned on, you can see a lot of the ceiling, but it still needs to charge for a few minutes for everything to be visible with them on, and then more like 15 minutes (or more) for them to continue to glow at a good brightness even with the blacklights off. You can prevent them from showing during a movie by simply not charging them. None of the theater lights point at the ceiling, so the normal lighting won't do a thing to charge them since they are all in the soffit pointing down. If I do want them to show during a movie, I can pre-charge them or even leave on the black light. The purple tones you see in the photo are a result of the residual black light taken by the camera from the stage light I have on the floor. In the one shot, it is much more obvious because I am taking a photo almost right at the place the black-light on the floor is facing. The other one you only really notice on the edges of the red soffit how it appears purple vs red. This is a longer camera exposure so the light bleeds in, and I left the floor light on to help the photo come out. The one photo which shows the screen in it has a very good representation of how the ceiling looks with all of the lights off and the room completely blacked out after the paint has been charged. (The milky way is painted, and is not a result of the black light purple) We did watch Interstellar with the ceiling charged but did not leave the black lights on, and by the end of the movie the glow had pretty much faded. I could leave the black lights on of course for the effect. I can't control the brightness of the ceiling as it is paint, and the black lights are non-dimmable .fluorescent bulbs, so I can't control how bright those are either.
In general a lot of your questions also relate to the fiber vs painted debate, which is a personal preference A painted ceiling looks much more realistic, but it also suffers from the drawbacks of glowy/reactive materials. Fiber lights can be turned on and off at a whim, no charging, but also look more artificial. I've seen a ton of pictures, but you can't even describe how amazing it looks when you blackout the lights with the ceiling glowing, it makes the whole ceiling appear curved and your eyes play tricks on you as they adjust. The stars even seem to twinkle as a natural reaction to the components in the eye adjust to the absolute dark. Throw on some ambient music too and almost everyone is blown away.
