The Blue colour represents the USB 3.0 Port. The speed of the Blue USB port is up to 5 Gbps (Gigabits per second). This type of USB port is found commonly in desktops and laptops. Here is the Blue USB Port, USB 3.0's connector pinouts diagram. Source: Wikipedia Red USB Port You might even find a Red Coloured USB Port. When a USB port is red, it indicates the port is USB 3.2. The Red USB port is even faster than the Blue and the Teal Blue USB ports. The Red USB Port transfers datastream at a speed of 20 Gbps. You would find Red USB Port (USB 3.2) inexpensive motherboards and hence are not commonly seen. Teal Blue USB Port Teal Blue coloured USB port is another type of USB port where USB 3.1 is present. This Teal Blue USB Port has a speed of up to 10 Gbps, two times faster than Blue USB Ports. This speed is breakneck and is ideal for large file transfers. Black USB Port Black USB Port is also known as the USB 2.0. This type of USB port is the most common USB Port ever seen. This Black USB Port is commonly used in desktops and laptops. This USB port was made to transmit data streams at much higher speeds than the USB 1.x versions. This innovation was a breakthrough as it can transfer up to 480 Mbps, about 40 times faster than White USB Port. Hence, this was also labelled as "Hi-Speed". Yellow USB Port Yellow USB Port is a special type of USB Port present in the motherboard. A Yellow USB Port denotes that it is an always-on Port. This USB Port can be a USB 2.0 or even a USB 3.0 port. White USB Port The white USB port is the earliest specification for the USB port. Generally, the white connectors are USB 1.x version. However, quite a few are USB 2.x compatible. The transfer rate is slow, which is up to 12 Mbps. Today, Macbooks have USB 3.0 ports as White USB Ports. So, you should not always consider white USB port means USB 1.x version. USB Ports Colour Demonstration Here, in these videos, find the different types of USB Port colours explained with detailed specifications. You will also get to know about how the different colour USB Port looks like. https://youtu.be/BplRBImLnc4 https://youtu.be/FaFssTu2PH0 FAQ’s on USB Port Colour Codes Is USB 3.0 blue or black?USB 3.0 Port is Blue USB Port.

Conclusion Though we are going through different colour coding for USB like Blue USB Port, Red USB Port, Teal Blue USB Port and many more, there are several cases where these colour codes are not always followed. So, it is better to check the motherboard specification, and for the laptop, it will be denoted by the text below the port. I hope you got a good idea about the different colours used to classify different types of USB ports.
