“It's blacker than anything you can imagine," artist Anish Kapoor, who recently acquired the rights to use the pigment “vantablack” in art, told the BBC in 2014. “It's so black you almost can't see it. It has a kind of unreal quality."
There is no darker color known than vantablack. Developed by a British company Surrey NanoSystems to use for military equipment like satellites and stealth jets, vantablack absorbs 99.96 percent of all light and can make the crinkliest piece of aluminum foil look like a flat surface. Vantablack isn’t a paint, though: it’s actually made by growing carbon nanotubes, which are ten-thousandth of the width of a human hair, Paula Cocozza reported for the Guardian in 2014.
