What color would you paint it?

[Herc Driver]

I fly over Houston and the Lake Charles area quite frequently, and have driven past the refineries numerous times as well. From what I've seen, the piping and distillation towers are various shades of silver, aluminum, white, and grays. The buildings have been made with just about every normal industrial material...blue or white metal siding, or brick, or hung glass, and generally colored a lighter color...though I doubt anyone actually gave consideration to matching the building color to anything else. There is always a lot of safety signs, and every plant has some sort of fencing and gate system for access with a guard shack at the controlled access points. You might want to visit the websites of the big name chemical companies and see if they have any background or marketing shots of the plant.
