Then the rest of the world should try and be more inventive, no?

Even if colour was switched, the different is still clear.People should observe rightly .Nobody is to be blamed. Danke

Thank you for the in-depth clarification.
It really make sense

Fun thing to note, this is basically just for the US. In the UK and Australia, (and most European countries) we use a white cross on a green background for most first aid kits, a green cross for pharmacies and both of them and the star of life for ambulances. Our medical planes have their own symbol too.

Thank you 🙂 Fixed!

Of course all that is true, but it doesn’t help with the fact that even if designers would get the colors right, it would just be an abuse of a protection symbol for military use instead of misuse of a national flag or symbol. The red in the Swiss flag does come from the Blutfahne (blood banner) so I understand how people would associate *that* with something health-related, but then again the Albanian flag also has a lot of red and isn’t used that way 🙂 Oh well, maybe I’ll replace “ignorance” with something more fitting.

As for the iso-standard first aid logo.
I think designers will keep preferring a red logo.
The association of red and health is extremely strong.
Red also stands out as a warning color and together with white it has great contrast.

I think you’ll see more Swiss flags in the future and a lot of them won’t be because of ignorance, not sure if that makes it better or way worse.. ?

Thanks for the suggestion, I’ve added a little history blurb and a link to Wikipedia. I first thought this is a very small and very specific issue, but what you wrote about the planes made me think. If it’s true that one person got this impression from video games, maybe a lot more people have. So the Red Cross is perhaps right when it complains that its symbol is now confusing people because it’s used wrong in video games (and even TV series, I have a few screenshots from Archer and Fargo for example).

The people who made Party Hard almost got it right on their ambulance, so it seems there are some designers who are discerning with their medical symbols. The only thing they got wrong is to put a red cross on top of the car. That pisses off the Red Cross but doesn’t make the Swiss chuckle.

I’ll try to dig up some more official alternative medical symbols that I could put on the About page in case more designers stumble over it 🙂 But I think the white cross on green, which is the very official first aid kit one, should be enough for medpack use.
