This is a video of The Action Lab’s James Orgill painting the entire interior of a room he made out of insulation board with the world’s blackest commercially available paint, Musou black, which absorbs 99.4% of light. He then turns on an overhead light bulb to see what it looks like inside. It looks…weird. My eyes did not like that. Of course my eyes don’t like much besides being closed and napping if we’re being perfectly honest. Although occasionally they do request I push on them really hard with the fleshy parts of my palms below the thumbs until I get a headache and see all sorts of painful colors and patterns, but that’s rare.

Keep going for the video, the reveal and experimenting begins at 3:30.
