That's an image of the M87* supermassive black hole, but it was created using radiotelescopes. The OP is asking about the *visual* appearance of a black hole to the human eye, not what it looks like in the microwave band. BTW, you should not post images on Stack Exchange sites without giving the source of the image (and a link, if the source is online).

Yes. There are a lot of crap depictions of black holes out there, and I think a list of pictures, both good and bad, would be helpful for the general public who search for them.

Apparently fictional Gargantuan from the movie Interstellar is a good simulation. I would expect something more on line with the top picture, with Doppler like shifts. I would say that any decent pic should be seen keeping in mind what exact phenomenon has been simulated (synchrotron rad, emission from external matter, rotation....) of it is supposed to be a global rendering in the vis.

The question in the body and in the title of the question are different. Which one do you want to ask?

Black holes are not visible. So the answer depends on what is around them and behind them.

Is there a safe distance in which a black hole can be observed with the human eye? What is a safe distance?

I have seen many computer simulated and artist renditions, and I am not sure if they depicted the true colors and shape of BH.

[This simulation](https://youtu.be/l36UkYtq6m0) (video link) has been made to show what a black hole might look like seen from different angles.

From [APOD](https://apod.nasa.gov/apod/ap200825.html) :

> If the black hole was surrounded by a swirling disk of glowing and accreting gas, then the great gravity of the black hole would deflect light emitted by the disk to make it look very unusual. [...] Surrounding the central black hole is a thin circular image of the orbiting disk that marks the position of the photon sphere -- inside of which lies the black hole's event horizon. Toward the left, parts of the large main image of the disk appear brighter as they move toward you.
