What color would you paint it?

Shaygetz and BR, thanks for the explanation as to why those colors are used. I like the idea of color coding the pipes... but I did not do that with the refinery. Still, that would really add some color to the scene. I looked around a little for some color classifications and so far have been unsuccessful but I've not given up yet.

The colors are the pipe colors (Yellow, Red, Blue, Green). The "Letters: should be placed near any valves or where a pipe changed direction So, once you figure out what each pipe carries (Fire suppression, a chemical, water etc.) you can paint it the appropriate color.
