In this video I paint my entire room with Musou Black to see what it looks like when the walls around you absorb over 99% of the light in the room. What happens when you turn on a light in the room?

    It's pronounced "moo-shoo" not "moh-soh". The dragon in Mulan (the Disney cartoon original) is named Musou. It means "unparalleled beast". It's also used in popular Dynasty Warriors games as a combo that can't be stopped. Thank you! XD
