There was a time when everything was easier. If the USB port was white, it was slow; if it was black, it was standard; and if it was blue, it was the fastest. That rule that helped us Easily identify USB-A generations It’s gone. The arrival of new standards, charging functions and brand marketing has meant that today we find a wide range of green, orange and purple ports that no longer mean much. Image: StorageReview The original color code. The current chaos, as we explain in our guide to the USB standardit was not planned. The USB-IF organization tried to standardize it: white corresponds to USB 1.x, black for USB 2.0 (480 Mbps), and blue (or turquoise) for fast USB 3.0 (5 Gbps). First confusion. That is a product of the charging ports: the first problem came when colors began to be used to indicate power functions, not just data transmission. This is how the yellow, orange or red ports arrived. These usually indicate an “Always on” or “Sleep & Charge” function, which means that the port continues to provide power even when the computer is turned off or in sleep. More speed, more colors. To differentiate USB 3.1 (10 Gbps) and 3.2 (20 Gbps), the standard suggested the color turquoise blue, or failing that, red. Here the system began to leak. And the final blow came from marketing. A purple USB cable for a Huawei device indicates that it supports SuperCharge, its fast charging technology. Image: Reddit The rule became extinct completely when the brands decided use colors as corporate identity. The most famous case is that of Razer, which dyes its ports a characteristic lime green. Likewise, if you see a purple port, it’s probably from Huawei. The Chinese manufacturer uses them to identify its devices compatible with SuperCharge (its fast charging system), although technically it is still a USB 3.1 port. Chaos also in names. If there is already a mess with the colors, there is also a mess with the names: USB-IF itself has contributed by renaming the standards. USB 3.0 was renamed “USB 3.1 Gen 1” and is now “USB 3.2 Gen 1.” In parallel, USB 3.1 is now “USB 3.2 Gen 2”. This makes it almost impossible for a user to know what they are buying without looking at the fine print, a mess that the Wi-Fi Alliance solved much more elegantly. with standards such as Wi-Fi 5, 6 or the most recent Wi-Fi 7. The real culprit: USB-C. The final nail in the color coding coffin is the USB-C connector. It’s just a reversible connector, but what’s inside is chaos: the same USB-C port can be a slow USB 2.0, a USB 3.2 or a very fast Thunderbolt 4. The only way to differentiate them is to look for the lightning bolt logo that characterized Apple. Or read the device’s spec sheet because color, unfortunately, no longer means anything.
