The Nazis had a wide range of symbols to identify prisoners as drug addicts, alcoholics, traitors, homosexuals, etc. for a wide range of reasons to help the guards know who they were dealing with.

Gays were considered to have a high rate of STDs because they did, so they were identified for the safety of the doctors, dentists and prison guards.

Bolsheviks were identified because the Germans were TERRIFIED the Bolsheviks would attempt another Bolshevik Revolution in which Jewish leaders mass murdered ten million Christians in Russia in 1917, only 20 years prior.

It's a similar and less politically correct system to our modern prison uniforms where orange represents "violent or unruly" behavior, blue for nonviolent "low threat", green for "suicidal" etc.

It's a security measure.
