Grey City, or Gray, How about Beige?
Another Idea that I had, that is quite on the same lines as my last one, but this one would be a musical (on or off Broadway) wherer the leading role finds themselves wakeing up in strange places. It would be a spectacular world with vibrant colors to appease the eyes. While the lead role goes to sleep things of undecided look or origin come and transport them to another location by actually changing the scenery, there would be some sort of evil cathcy tune sung whilst they work away. The lead would than awake in this strange place and try to find their way home. Kind of Dark City meets Alice in Wonderland...
