Interesting fact I got from IFLS.
Eigengrau is the shade of black seen by the human eye in complete darkness.
This isn’t any old shade of black, it is precisely #16161D. With no available light to contrast objects against one another, it is possible to be in the presence of items that are darker black without being able to perceive them that way.
I changed the color of a couple of elements around the blog to Eigengrau, just because it’s cool and kind of geeky!
