NASA actually created an animation simulating what it would look like to fall into a black hole. In short, you’d see the outside universe warped into a circle directly opposite the direction of the singularity, with black all around it. This is ignoring the accretion disk that the other commenter pointed out, although that sits well outside the event horizon and I’m not sure off the top of my head how much of that light escapes inwards towards the black hole versus outwards.
