How black is black [View all]

Here's a pretty neat article on a spray paint called vantablack. They have a form of vantablack which is made of grown nanotubes. But they have developed a spray on paint version. It blocks 99.8 of the ultraviolet, visible, and infrared light shown on it. One of the stranger pictures is of 2 facial masks. It doesn't look like they could be the same object with one just having the paint on it.
