That top one is really obscure. Who dug that up?

The poster of signs. You'll find lots of sources on the web. I took that from either wiki or the USHMM site. Must have printed a lot so the guards could tell the prisoners apart. Maybe they were color blind.

Facebook wouldn't object to this.

Resistance patches so you can identify yourself or your writings.

I could be mistaken but I believe those charts may have been camp specific. They’re often identified by camp, and there were a lot of other categories which weren’t on there. POWs got an uninverted red triangle, so those traffic signs are bad. Roma males brown. And there were more sub-classifications than that chart shows. Which is what makes me think they’re camp specific.
