The first feature that is characteristic of black holes is in their name, that is ‘black. ’ Black holes are black. The force of gravitation on the event horizon is tremendously stronger, to the level that even light cannot escape. Here, the meaning of the black is the lack or even the complete absence of light.

We also use the principle of referral where we associate black with the lack of colour. But that would mean there is a way to coat it in black—and colour so to speak—as long as colour interpretation here prioritised quantum chromodynamic charge.
