The same real black hole, printed in negative. Space is white. The light is ink.
Every pixel follows one ray of light back through the bent space around a black hole that does not spin. The rays that skim past the edge loop round it, which is why you can see the far side of the disk above and below the hole.
The colours are a photographic negative. Where a normal picture is bright, this one is dark. The hottest gas, nearest the hole, is the deepest ink. The side of the disk turning toward you is darker than the side turning away, because its light is boosted.
Pick any colour for space and for the hole. The physics stays the same.
