I think you'll find that rather than the colour of a television tuned to a dead channel, the sky in Vancouver instead looks like this: "It rains a lot, up here; there are winter days when it doesn't really get light at all, only a bright, indeterminate gray. But then there are days when it's like they whip aside a curtain to flash you three minutes of sunlit, suspended mountain, the trademark at the start of God's own movie." (Opening lines of "The Winter Market".)
