Blue is the indicator for dry chem. I think it is a NATO standard to have the extinguishers in that colour. The Brits used blue in civilian use until 97, when all the bodies went to red with an indicator stripe allowed to be the indicating colour (blue in this case).
Not sure what Canada's standards are. The US uses the ABC circle and traingles.....who the hell remembers what they all are. The Blue Ansuls are ABC so you can shoot it at just about any fire.
The extinguishers are still nationally stocked in the supply system, and in blue. I suspect any red ones in the system may have been either local purchase or been introduced as EIS with new (non-SMP) vehicles.
