What are the different symbols sewn onto the uniforms that represent the different prisoners in the concentration camps?

In concentration camps, prisoners were often forced to wear uniforms adorned with various symbols to denote their backgrounds or offenses. A yellow Star of David identified Jewish prisoners, while red triangles indicated political prisoners. Other symbols included green triangles for criminals, blue triangles for immigrants, and pink triangles for homosexuals. Each symbol served to dehumanize and categorize individuals, contributing to the systemic oppression within the camps.
