Who can tell me what color the hats of Wuxi Murata Electronics, Sony Electronics and Alpine Electronics are?

In the Alps, department heads and above (section heads, ministers, etc. ) is just a work hat, just like ordinary telephone operators and office workers. There is no special logo, but men's and women's clothes are different, but there are still some differences from vice squad leader to team leader. There is a blue line (one) beside the vice monitor's hat, and the monitor has two blue lines. The deputy team leader's hat has a blue line on each side, which is perpendicular to it, while the team leader has two blue lines, which are also perpendicular to it. The security guard (mechanic) is a black hat. Parts delivery is red. Police tactical unit is a fireman (in short, staying and evacuating people in case of fire). That's about it. Pay attention to badges. People with red belts around their necks are usually leaders. Blue is the average person. There is a line on the badge. The blue ones are regular workers, the red ones are dispatch workers and the yellow ones are interns.
