Sex Work and Pink Light
I believe everyone who has visited or read reports about a sex work venue notices the pink/reddish light bulbs or tubes, and so the term "red light district" is derived. But do you know what the pink/reddish light is for?
Due to the current laws and legal regulations, sex work is different from other industries and cannot be advertised. What they rely on is the tiny pink light bulb, placed in front of the window or outside the door, to attract the attention of potential clients.
In addition, many sex workers work independently. Like other business owners, they spend a lot of time decorating their rooms where they run their business. All kinds of decorations, including the pink light bulbs, aim to make the guests feel relaxed and comfortable, and enjoy the service in an amorous ambiance.
In fact, the soft pink light is like a magic wand, in addition to boosting the ambiance of the room, it can also add charm to sex workers and make them look their best.
