Well the last "real" darkroom I worked in was back in the early '70s and it was OD green ( as were my clothes, vehical, and everything else in my "world" ). Since those days I have had numerous bathrooms and basement rooms which I have used, but have not had a dedicated darkroom. I am now getting ready to dedicate a part of my house for use as a darkroom. As I was looking at the thread showing pictures of peoples darkrooms I noticed most were white. I would have thought that you would want them black, at least the walls around the enlarger. I can understand that the safelight might reflect better off white walls, but I would think you are also bouncing ambient light off your enlarger onto your paper. Am I missing something?
