Black holes are Pink.
Actually, professional astronomers have long been happy with the idea that black holes could be a brilliant blue-white colour. They are thought to form when massive stars come to the end of their lives. Luckily for astronomers, and very strangely, some black holes shine incredibly brightly. They are so bright that if you replaced the Sun with a quasar, it would vaporise the Earth in less than a second. Imagine that there was a black hole at the back of this room.
