Type 99 police uniform shirt originally had three colors: iron gray, light blue and white. The original purpose was to distinguish police ranks. Police cadets, police officers and superintendents wear iron gray shirts with silver gray ties, police supervisors wear light blue shirts with dark blue ties, and police supervisors wear white shirts with dark blue ties. In 2000, shirts were still in these three colors, but their functions were adjusted. The police chief wore a white shirt with a dark blue tie, all police officers below the police chief wore a light blue shirt with a dark blue tie, and all police officers and police academy students wore iron gray shirts with silver gray ties except those below the police chief. In 2006, the Type 05 jersey was reissued, and the color of the captain's jersey remained unchanged. All police officers below the captain wear light blue shirts with dark blue ties. Iron gray shirts and silver gray ties are invalid.
