certain USB ports come in yellow, red, and other shades. You might be interested to learn that these hues are not for decorative reasons but form a color coding system that signifies the distinct functionalities of each port. The colors assist in differentiating between a USB 2.0 port and a USB 3.0 port.
If you’ve come across a red USB port previously, it is probably a USB 3.1 Gen 2 port. This advanced USB standard accommodates data transfer rates of up to 20 Gbps. Frequently, they serve as “always-on” charging ports, also allowing devices to be charged even when the computer is powered down.
Nonetheless, it is important to recognize that there is no worldwide standard for these colors. The USB Implementers Forum designates the colors, but that’s about it. They are specified, yet they are not mandatory for manufacturers, meaning a red port on one device can be entirely different on another.
