If you close your eyes in a completely dark room. When you open them, the color you see is called eigengrau, which means intrinsic gray. It's the shade of dark gray people see when there's no light.
Wow, that's so interesting! I had no idea there was a specific name for that color we see in total darkness. Itās kind of wild to think about how our eyes still perceive something even when thereās no light around. Next time Iām in a dark room, Iāll definitely remember that eigengrau moment!
