“The article quoted an unidentified French fashion expert as saying that the North Korean leader’s style was followed internationally. ‘Kim Jong Il mode, which is spreading expeditiously worldwide, is unprecedented in history,’ the stylist said.
    The 68-year-old leader’s suit comprises a zip-up tunic and matching trousers, usually in khaki or blue-grey. In winter he also wears a shapeless anorak and fur hat.”

“Fans of Ota’s running man point to two key advantages: It’s a pictogram,
and it’s green. The sign’s wordlessness means it can be understood even
by people who don’t speak the local language. And the green color, they

“Eigengrau (German: ‘intrinsic gray’), also called Eigenlicht (‘intrinsic 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 lighting 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 contrast provided by the stars.”
