You probaly notice it straight away because suddenly there is something that does reflect light, or nothing which blocks it anymore.

Lets say you have a house on a remote hill with a balcony filled with torches and other lights. As you stand ontop of the balcony you will see loads of stuff barely because everything reflects light. You will see the edges of the forrest. You might not see it well, but you will percieve something.

If we then put a big screen (lets say 2 meters by 2 meters) with this collor somewhere in the edge of the forrest you will suddenly see a square of nothing. It will be visually diffrent because of the contrast. You cant see it, but because you can see the rest barely you still percieve it as something being there.

If we remove the screen then you suddenly would notice the square of nothingness disseapering.

I'm going for the save here - I think he'd trying to say that you would infer that something was there by the fact that absolutely nothing is there - a null space. Like a black hole you can't see it but infer it's existence by knowing something should be there, even if it's the stars behind it.

This painted diamond I think would be obvious as it would be a big black nothingness in the middle of the room. It's black not invisible.

Or, in a hell of a lot less words: You can see the very dark black thing. You would be able to notice if you couldn't see the very dark black thing.

You will see a black screen, it wouldn’t be nothing, it isn’t invisible. What this paint does is prevent you from perceiving the shape of the object. So from afar all you can see is the 2m x 2m frontal area, you wouldn’t be able to tell the difference between just a screen from any other shape.
