the color of darkness:
"eigengrau (german: intrinsic gray), also called eigenlicht (intrisic light), dark light or brain gray, is the color seen by the eye in perfect darkness. even in the absence of light, some action potentials are still sent along the optic nerve, causing the sensation of a uniform dark gray color.
eigengrau is perceived as lighter than a black object in normal ligthing conditions because contrast is more important to the visual system than absolute brightness. for example, the night sky looks darker than eigengrau because of the constrast provided by the stars."
