Decoding the meaning of the colors of the USB port

You can see the USB terminals of the peripherals are dyed in different colors. And they all have their own meaning to distinguish.

USB ports are often “dyed” by manufacturers for different colors such as blue, red, white, and yellow. But people don’t just do it to look good, often it will help you distinguish the standards of that USB port. The following is an article about the meaning of the colors on the USB port, please join us in decoding.

This is the usual color of USB 3.0 ports and is one of the main ways to distinguish it from other standard USB ports. This standard supports data transfer rates up to 5 Gbit/s. Devices and cables connected to this port must also meet a speed of at least 5 Gbit/s to benefit from it.

If you pay close attention, you will see that this port is a bit lighter blue than the blue of the USB 3.0 port. It supports speeds up to 10 Gbit/s. Sometimes it is also green. Since it’s a high-speed port, it’s also ideal for plugging in devices that need high speed, typically an external hard drive.

Any USB port that is red is a USB 3.2 port. This version is even faster than 3.1, reaching maximum speeds of up to 20 Gbit/s. Many motherboard models now support this USB standard, especially high-end models.

The black color of the USB port indicates it is a USB 2.0 port. This is an old standard and the speed is also low, only 480 Mbit/s. This is the ideal port for you to connect devices that do not need too high speed such as mice, keys, headsets, etc. Although it is quite old, this port is still used a lot on today’s motherboards because of the cost. low as well as its usefulness.

The white color on the USB port indicates it is USB 1.X, which is a very old color standard. It supports very slow speeds of 1.5 Mb/s or as high as 12 Mb/s. You can only see this port on older computers if you have one. Today, it is considered “extinct” on PC.

Unlike other colors, yellow does not indicate the standard of the USB port, but indicates that it is always on, even when you turn off the device. If you have a charger for your phone, camera, or other devices that can be charged via a USB port, you can plug it in to make sure it’s always charged. If you have a laptop with a yellow USB port, you have a power bank.

Usually you can find out the standard of a USB port by looking at its color. However, the color of the USB port standards is not a standard. For example, the yellow and blue ports can both be USB 3.0. There are also some black USB 3.0 ports. In such cases, we have another way.

If the USB port has the word “SS”, it is USB 3.0, and the word “SS 10” means it supports 10 Gbit/s.

USB 4.0 is the latest standard today, it has a maximum data transfer rate of up to 40 Gb / s (equivalent to 5 GB / s) twice that of the USB 3.2 standard. This standard is also capable of transmitting power up to 100W. This port is suitable for powering and outputting high resolution monitors (or multiple monitors) with a single cable. In addition, it is also more than capable of doing well with lower-demand tasks such as transferring data or plugging in a mouse and keyboard.

The USB 4.0 port does not have a representative color, its main port form will be a USB Type-C port that can be plugged in, unlike the traditional standard, which is a USB Type-A port. At the time of writing this article, USB 4.0 still does not have a conventional color.

Above is the meaning of the colors on the USB ports. Hope this article has brought you useful information. Thank you for your attention.
