WHAT COLOR.. are / is the darkroom(s) you have ever visited or used? why do people "follow" others when it is WRONG?! A darkroom, if it is truely dark,, would still be DARK.. even with white walls, white celing, etc. so what is the purpose of painting a darkroom BLACK ? it is WRONG! ONCE YOU SEE THE DIFFERENCE. only then will you UNDERSTAND.. why WHITE.. has to be the color to paint those walls! I have worked in darkrooms 7 am till midnight for years many years. and there was no fatigue.. you can't do that in a BLACK ENVIORMENT. your eyes get too tired, you can't see as well. and the "pools" of light from the safelight are more of a hinderance than helpful. with white walls that safelight reflects, just as Kodak intended.! You just can't go wrong.. taking Kodak's advice!
