What do Alpha Complex corridors look like?


Cosmic Mongoose
So I’m hopefully start a game soon with a group of new to Paranoia players and just wondered how people describe the various areas of Alpha Complex? I can see ultraviolet corridors being all sheening white high tech looking but what about the lowers levels? I see them being base grey concrete with 1m tall colour bands running along the center of the walls, this way all the tech and stuff does have to be coloured the same as the clearance. Anyone else have ideas?
Maybe go with it by ranks.
It gets better with each rank.
Red is, all broken down and painted over.
Orange is the same, but scrubbots clean it once in a while and the cables aren't loose.
Yellow actually has the pipes covered.
Green is clean and has posters with slogans. Etc..
