2. USB connector interface definition (color)

I wonder if you have noticed that USB ports come in different colors, black, blue, purple, red, yellow, etc. Do you know what the different colors of USB ports mean?

These colors are not required by the USB specification and are not consistent across device manufacturers. For example, Intel uses orange to represent charging ports, while one manufacturer of industrial equipment components chose orange to represent USB ports with a strong retention mechanism.

White, black, dark blue, and cyan are mainly related to transmission speed.

Purple, green, yellow, red, and orange are mainly related to charging.

Summary: USB port color is one of the ways to identify USB types, and most manufacturers still follow a similar color pattern. But it is not a standard and recommended method to identify USB types.
