Yeah, it amazed me too. Not to mention the durability and quicker recognition by colour. And that $1 notes and the low coins still exist.

If the population is too immersed in tradition, win them over with the coolest notes ever. Something using dark blue and dark red with white/silver could look awesome. Rather than what we have in Australia, Canada and Europe where there are 5-6 completely different colours used, one for each note.

I wondered if it's something to do with patents? Australia's RBA has a subsidiary that prints notes for various countries. Maybe there's a competing technology that Canada is using?

I quite like that and never really understood why US bills are only green. If I look for 50€ in my wallet, I’m going to skip over the blues and greens and essentially directly pick the right orang-y one.

I’ve also never seen anyone suspicious of 50€, people sometimes look funny if they see 100€, but even that happens rarely.

I appreciate the differences too. And as with you, I've never seen anyone check a banknote suspiciously in AU or EU, but I have many times in the US.
