Sorry, not sure if this is the right place for this. I'm trying to find a definitive list/examples for the colours of CO2, Oxy, Argon etc compressed gas cylinders. I appreciate that, for the most part, they are various shades of "drab", I was just wondering what a) the underlying (civvy) colours were and b) what was used to differentiate what gas was in what cylinder. And yes, I have been Googling without much joy! 🤪
Many thanks for any links etc.
