It's definitely a good look and not at all new - in the Victorian era, brass hardware and black ceramic knobs were a thing.

To make it work, the knobs need to be a different material (ceramic), and you need to have a brass faceplate behind the doorknob to tie everything together.

Then pick sleek modern hardware - that definitely works too (but you still need the brass faceplate).

The black ceramic plus brass is a timeless combo - I've seen it work with super ornate Victorian styling as well as minimal modern styling.

No. Match the hinges please. The Emtek looks great. In either matte black or satin brass. Pick ONE. Door hardware is a nearly forever element. Do it once, and do it right.

I’m returning to an old post, but I have a somewhat related question. I have black hinges in my daughter’s room and a black door handle on her room door, as well as black on the perimeter of her windows. Her room is painted two shades of pink. She has a white built in wall unit and I am adding white, brass, and sore color knobs to the built in. The question is, for her closet bifold doors should I go with black handles to match the hinges and the door handle to the room, or with white/brass to go with the knobs on the built in?

Sorry I meant to write that I am adding “white, brass, and rose color knobs to the built in”. So essentially nothing black in the actual room decor or the rest of the hardware besides what I described above.
