If we were to shine a light into vantablack in a dark room ~0.04% would be reflected but it would be enough make the object visible. So, it is possible to differentiate both paints in those conditions.

- perl4ever 7y agoSomebody went and took a picture of the vantablack car that wasn't set up to make it look dark and showed it appeared to be a dull gray. There's a very high degree of latitude in how you take pictures of something, and the 0% brightness level in the output can be anything you like. The human eye is adaptive, as well, so it probably wouldn't be all that impressive in person either.
