Does a color coding table exist, that lists the colors to use in a GUI to display piping. I am looking for the colors of DI water, N2, HCL, HF, KOH and so on. I would appreciate any help.

 

One thought comes to mind is to use Standard ASME A13:1 "Scheme for the Identification of Piping Systems".

 

I don't know if it's included in a standard but in many chemical companies in switzerland I have seen the same coding :

water : green
N2 and other gaz : yellow
Acid : orange
Caustic : violet
