Man that was both fun and educational!
Complicating the discussion even more, US Navy Diving used this color code for years:
Air = Black
Exhaust = Silver
Helium = Buff
HeO2 = Burn Orange
Oxygen = Green
The current Navy standard is:
Table 21-1. Recompression Chamber Line Guide, page 21-4, U.S. Navy Diving Manual.
Air (High Pressure) = Black
Air (Low Pressure) = Black
Chilled Water = Blue & White
Exhaust = Silver
Fire Fighting Material = Red
Helium = Buff
Helium-Oxygen Mix = Buff & Green
Hot Water = Red & White
Nitrogen = Light Gray
Nitrogen Oxygen Mix = Light Gray & Green
Oxygen = Green
Potable Water = Blue
Naturally, the only color common to commercial gas suppliers in the US is green for O2. Attached is an image how color coding is used on some mixed gas control panels. When the whole area is a spaghetti recipe of hoses, pipes, valves, and cylinders; color codes are really important.

Tank and valve color arent what the thread was about.
I can see in a commercial or navy supplied gas dive, you need those colors to make it completely obvious what gasses you are adjusting.

Wow.
I'm not going to rehash this entire effing thread. Read the whole thing before you start posting on a 2 year old thread.

Does a trimix tank sound any different when it explodes than a Nitrox or air tank?
Does it even make a sound when there's no one around to hear it?
