I was recently reading through Anton Gill's 1989 book "The journey back from hell" regarding the experiences of concentration camp survivors.
On p.31 of this book he mentions that
There were several thousand priests, and members of religious orders of both sexes, in the camps
I do realize, as is shown in this other question, that Jehovah's Witnesses wore the purple triangles. According to Anton Gill's book there were 6000 of them in the concentration camps and he says (on the same p.31) that "they attracted the special enmity of the Nazis". So I am not sure if these are the reasons why they had their own triangle color.
Anyway, presumably they were not the only religious group, besides Jews of course, that was represented there mainly because of their religious beliefs(?)
For example, according to this Wikipedia article 2720 clerics were incarcerated at Dachau.
The question I wanted to ask is: what color triangles were assigned to the members of other religious groups, i.e. those that were neither Jews or JWs?
