People walk outside a pavilion at the PyeongChang Olympics, nicknamed the super-black building. It was designed by British architect Asif Khan and built by Hyundai. /VCG Photo

The building exhibits the super-black effect as it uses vantablack, the world’s darkest material that reflects so little light it’s described as the closest thing to a black hole. /VCG Photo

Vantablack was first developed by Surrey Nanosystems, a British company, three years ago. /VCG Photo
