The sky above the port was the color of a television tuned to a dead channel.

>>>> Gibson, William. Neuromancer. Ace Books, 1984.

Gibson imagined an ancient TV ... that grey/green haze as the tube warmed to a channel that was 'active', but sending no programming. A 'dead' channel.

Most kids in the 90's imagined the static of a TV of THEIR childhood, when not tuned to any channel, just projecting a grey/white static. Gibson has often corrected people that this was NOT the 'Dead Channel' he was referring to.

Now, of course, a new generation is imagining a sickly bright blue ... probably the last generation to really know what a 'TV' is, when it connected to something called a 'channel'.

EDIT

As noted below, it's fair to say it may have been static. Gibson seems to sometimes contradict himself with all the interviews he's done, and there's probably no way to know. I just wanted to note that there's three ways of looking at it. Though, the 'blue' wouldn't have been possible, since TVs didn't have that function until well after the book had been published.
