USB, which stands for Universal Serial Bus, ports are created to link two different, yet compatible, electronic devices. For instance, you can connect a mouse’s cable to a computer’s USB port. The majority of current electronics feature at least one USB port, ranging from televisions and gaming consoles to computers, and if you observe closely, you’ll notice various colors inside the port. While it may seem purely decorative, there is more significance to it. Each port color denotes a distinct functionality, and attaching your device to the correct USB port can significantly enhance speed and performance.
White, black, red, and yellow are just a few colors you’ll recognize within a USB port. There isn’t an industry standard established by the USB Implementers Forum (USB IF) that specifies what each color represents. However, most manufacturers adopt these colors as an informal standard to indicate their functionalities. For instance, using a red port suggests that your device may continue to charge even if your computer is powered off. Such ports are frequently utilized by brands like MSI and Gigabyte. Since this coloration is not obligatory and simply a recommendation, you might find some companies employing black USB 3.0 ports instead of the typical blue ones, like those found on the HP Omen 25L. Thus, let’s examine each USB port color closely and uncover its role.
