I see that blue is the preferred color for kerosene here also. Green is for oils or mixed gas. I might paint my Jerry cans to the standard
That Proquip fuel can looks like a fantastic bit of kit. Love the rebated welded seam, someone studied the original Jerry can when designing that. Well done. I stuck with standard color coding for my Jerry cans. Not sure it matters much when the lettering plainly says GASOLINE, but figured more clarity is good when it comes to flammable liquids.
As I am quite sad, a Trangia 500ml bottle with the 100 year logo. There is now a clear strip to show the fuel volume as well, which is nice.
