For film there is no analogous situation at all as there should be no light present to reflect.
There isn't any discernable pink cast to anything in my red and black darkroom. Its lit by lights, not lights pointed at the walls. Checking with my color meter, it rates around 3100k, no shift. Very close to the walls I can get it down to 2700 and some magenta showing.
Gzzorrkk! Loud colors would be distracting. Not my idea of any place to evaluate either black and
white prints or esp color ones, or be trying to subtly tone them. But then, I don't like music in the darkroom either. I don't know how Fred Picker managed to print with Bach and Beethoven. I personally got a gout attack from listening to Handl while watching Barry Lyndon and all those frumpy
Englishmen eating pheasant and drinking port.
The one darkroom I built and painted flat black, I never got around to completing and using, and all my other darkrooms were converted rooms, used as is, meaning whatever was there before it became my darkroom, and I don't believe I ever had a problem, other than noticing the after glow of the florescent lights.
Even the luminous paint on an old-school Gralab timer will fog certain films in trays. So will red LED's.
I put timers below the sink, where the film can't even see them. And no light trap it totally light tight. Let your eyes adjust long enough, then look at the film swishing in the tray, and see if there is any perceptible reflection at all. All enlargers leak light somewhere around the carrier. Most are
quite bad in this respect. Your paper might not get fogged in typical circumstances, but what if you
are projecting an image onto film, say for an enlarged neg, dupe, or interneg? Whole new ballgame.
Black wall, black countertop, black everything. Even handling film can generate static in cold dry
weather if you don't know how to suppress it. My film room is behind a darkroom, which is behind
yet another one!
I also shine my safelights off the walls, on purpose. You just have to test.
I understand Drew's point, but when I load film holders or developing tanks I turn the dial toward the wall (which is currently black until I get the real darkroom built - hanging black plastic as I mentioned) and I have no LEDs on. I develop in daylight Jobo tanks so no worries there. When I used deep tanks I used a countdown to beep timer that's not illuminated, but though I still have the tanks and thought about using them with Diafine, I haven't used them in years. So yeah, when I'm working with film that's different, and I work accordingly.
Presumably if your darkroom was painted red you wouldn't need safelights at all. As long as all the light was being bounced off the walls and none spilled directly from the lamps.
