The reason why the room was pink was because on black and white film, hues of red become dark shades of black. Pink is the perfect balance to give it that dark creepy grey.
A related fun fact: while old black and white film was under-sensitive to reds, it was correspondingly over-sensitive to greens. Actors whose characters were meant to have unnaturally pale complexions - like Morticia Addams - would often take advantage of this by wearing makeup with a green base tint in order to make their faces “pop”. This is where the modern trope of cartoon vampires having green skin comes from.
These are some fun fucking facts

"I have noticed that when all the lights are on, people tend to talk about what they are doing – their outer lives. Sitting round in candlelight or firelight, people start to talk about how they are feeling – their inner lives. They speak subjectively, they argue less, there are longer pauses. To sit alone without any electric light is curiously creative. I have my best ideas at dawn or at nightfall, but not if I switch on the lights – then I start thinking about projects, deadlines, demands, and the shadows and shapes of the house become objects, not suggestions, things that need to done, not a background to thought."
