Never seen a singularity so would have to agree it doesn’t. Visible Event Horizons are made up of matter that does reflect light, but if there is no matter involved only light you would likely see is distorted as it passes through it from other sources
No event horizon is made up of matter. Do you mean the matter around and behind the black hole, by which the location and size of the black hole can be inferred?

Yeah that’s what I was referring to
