Is black light a thing?

I already posted on r/nostupidquestions before anyone redirects me there.

Also, before you say that’s literally just darkness, just hear me out please lol. Despite it being called a lightbulb, can a lightbulb, or just bulb, emit light that is the color black? This sounds pretty damn stupid but bear with me. I was daydreaming today, not while typing this post, about a house with light bulbs that emit all different colors, including black.

Is this possible at all in real life? Can a bulb create the color black without the influence of any external environment, in the same way light bulbs create sparks of incandescence that become light? Can you create a shadow out of thin air, with nothing around it?

I get that this was originally about whether we could make whatever black light is to help see in the same way a normal light bulb works, but now I’m more curious
