#1: The Real Color of a Pitch-Black Room
Ever open your eyes in the middle of the night, in a pitch-black room, and wonder exactly what shade of black that color is? Or wonder if that color has a name? Well, maybe you haven’t, but it’s interesting to learn more about this color shade that is so prevalent in our everyday lives. Eigengrau is the color you’ll see if you open your eyes in a pitch-black room!
Eigengrau is often called either dark light or brain gray, which actually makes a whole lot of sense the more I think about it. This is both the color we see when we close our eyes, as well as if we open our eyes in a pitch-black room. We see this color because our eyes actually can’t see true darkness! So, the next time you open your eyes in the middle of the night, you’ll be able to really think on the shade of eigengrau you’re seeing. Or not.
