Not all USB ports are the same color. Maybe you hadn't realized, but each USB port you have on your computer, your television or any other electronic device has a different color.
Why is this happening? You may think that this is simply a whim of the device designer, but that is not the case. Each USB port has a different color to indicate the capabilities of that port.
Didn't you know? Maybe you have several ports on your device and one of them is the most powerful, that's why it will have a different color. In fact, to be clear, there is a color code approved by the USB Implementors Forum, the organization that is responsible for managing everything related to USBs in the world.
So if you want to know what each color means and what the performance of each USB is, to know which one you should use at all times or if a USB port is not working correctly, pay attention to this article.
USB port color coding
There are six types of USB port colors - look at your computers and you will see that there is a variety - and this is what each of them means:
-White: These are the most common ports. They are also the oldest, and refer to the USB 1.x standard. For this reason, they are the slowest ports, with speeds between 1.5 Mbps and 12 Mbps.
-Black: A black USB port represents the USB 2.0 standard (also called Hi-Speed USB) and is also very common. Its data transfer speed is better, reaching 480 Mbps.
-Blue: They are also becoming more common. They represent USB 3.0 technology, also called Super-Speed. They greatly increase the data transmission speed, reaching over 5 Gbps. For example, you will find them in external hard drives and equipment that needs to transfer data at high speed.
-Red: They are no longer so common, and are identified with the standards USB 3.1 Gen 2 and USB 3.2. Sure, they're much faster, with data transfer speeds ranging from 10 to 20 Gbps. Additionally, they are usually "always on", so if you have a device connected to them on your computer, they could charge it even if the PC is turned off.
-Yellows: These USB ports can be USB 2.0 or USB 3.0 and are also always on, so they can be used to charge devices.
-Oranges: They are the rarest, and are similar to the yellow ones. They provide passive power and meet USB 3.0 standards.
