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
Moment of bravery at the vet
My grandpa has Alzheimer’s so he has no idea who my grandma is but everyday for the last three or four months he brings her in flowers from their garden and asks her to run away with him and be his wife and everyday she says she already is and everyday the smile my grandpa gets on his face is the most beautiful heartfelt thing I have ever seen.
