Like most European countries have blue police uniforms, all German State Police Forces (German: "Landespolizei") and the Federal Police (German: "Bundespolizei") have shifted to blue uniforms to conform with the common blue image of most police forces in Europe. In line with the uniforms, police vehicles and various items of equipment also changed the color to blue. Although there are 16 states, currently only six types of state police uniforms are in use, because many states co-operate in the design and sourcing of the police uniforms.
