The only time something doesn't reflect light is if it's painted in that special black that's even darker than vanta black, because that's what makes it so black; it absorbs all light instead of reflecting any.

And even that reflects a teeny tiny bit of light.

A coating, which is made from vertically aligned carbon nanotubes. Absorbs 99.995% of visible light. Vanta: A mere 99.96%.

Black holes don't reflect any light at all as far as I know. They do emit some light via hawking radiation, but that's not really reflecting.
