Screens arent as sensitive to light as photographic films and the yellow light allows better visual inspection of your coating.Concerning the color of the walls again black was used to keep any light from reflecting and exposing film, a good idea but very hard to work in with a red safe light. Lighting is required to be placed so that all areas of the swimming pool are clearly visible and without glare. Harsh, usually fluorescent, overhead lighting often creates the same problems.
