The rainbow effect is achieved by a process called anodizing. Metal badges are casted or stamped in a mold firstly, just like any other pins. Before any enamel is added, the metal pins are carefully cleaned and prepared for the anodizing process. A chemical solution is created, and the pins are submerged into it. A grounding wire is then attached to each pin, and an electrical charge is then passed through the metal with a wire. The chemical reaction with the electricity creates an amazing rainbow effect on the metal emblem. This process only needs to be done for a few seconds to change the metal’s color. The colors shift and change depending on how long the process is applied to the pin. Applying the electricity for even half a second more can drastically alter the metal’s color.

Due to the nature of rainbow plating, variations in color will occur and each pin will be unique. And if you reorder the exact same thing, there may likely be batch-to-batch variation.
